Abstract

A major credit shock can induce large intra-day variation margin payments between counterparties in derivatives markets, which may force some participants to default on their payments. These payment shortfalls become amplified as they cascade through the network of exposures. Using detailed DTCC data we model the full network of exposures, the shock-induced payments, the initial margin collected, and liquidity buffers for about 900 firms operating in the U.S. credit default swaps market. We estimate the total amount of contagion, the marginal contribution of each firm to contagion, and the number of defaulting firms for credit shocks of different magnitudes. A novel feature of the model is that it allows for a range of possible responses to balance sheet stress, including delayed or partial payments. These `soft default' options distinguish our approach from conventional network models, which typically assume that full default is triggered whenever the default boundary is breached.

Abstract

A VAR model estimated on U.S. data before and after 1980 documents systematic differences in the response of short- and long-term interest rates, corporate bond spreads and durable spending to news TFP shocks. Interest rates across the maturity spectrum broadly increase in the pre-1980s and broadly decline in the post-1980s. Corporate bond spreads decline signi ficantly, and durable spending rises signi ficantly in the post-1980 period while the opposite short-run response is observed in the pre-1980 period. Measuring expectations of future monetary policy rates conditional on a news shock suggests that the Federal Reserve has adopted a restrictive stance before the 1980s with the goal of retaining control over inflation while adopting a neutral/accommodative stance in the post-1980 period.

Abstract

In this paper, we show that unemployment increases child neglect in the United States during the period from 2004 to 2012. A one percentage point increase in the unemployment rate leads to a 20 percent increase in neglect. We identify this effect by instrumenting for the county-level unemployment rate with a Bartik instrument, which we create as the weighted average of the national-level unemployment rates across each of twenty industries, where the weights are the county-level fraction of the employed working-age population in each industry at the start of the sample period. An important mechanism behind this effect is that parents lack social and private safety nets. The effect on neglect is smaller in states that introduce longer extensions to unemployment benefits, and is greater in counties where an initially larger fraction of children are not covered by health insurance. We find no evidence that the effect is driven by alcohol consumption or divorce.

Abstract

We model the power of media owners to bias readers’ opinions. In particular we consider readers that have “correlation neglect”, i.e., fail to understand that content across news outlets might be correlated. We study how a media owner who controls several outlets can take advantage of the readers’ neglect. Specifically, we show that the owner can manipulate readers’ beliefs even when readers understand the informativeness of news outlet by outlet. The optimal strategy of the owner is to negatively correlate good news and positively correlate bad news. The owner’s power is increasing in the number of outlets she owns but is constrained by the limited attention of readers. Importantly, our analysis suggests several new insights about welfare in media markets. First, measures of media bias have to take into account the correlation between news outlets. Second, media-market competition curbs the ability of owners to bias readers’ beliefs. In particular, we show that readers always benefit from breaking conglomerates, even when all the new media owners share the same bias. Finally, we highlight a potential cost of media diversity. When readers have correlation neglect, diversity in the interests of owners might lower the informativeness of news content.

Abstract

This paper provides a revealed preference characterisation of quasi-hyperbolic discounting which is designed to be applied to readily-available expenditure surveys. We describe necessary and sufficient conditions for the leading forms of the model and also explore the consequences the restrictions on preferences popularly used in empirical lifecycle consumption models. Using data from a household consumption panel dataset we explore the prevalence of time-inconsistent behaviour. The sophisticated quasi-hyperbolic model provides a signi ficantly more successful account of behaviour than the alternatives considered. We estimate the joint distribution of time preferences and the distribution of discount functions at various time horizons.

Abstract

What are the long run consequences of planning and providing basic infrastructure in neighborhoods, where people build their own homes? We study "Sites and Services" projects implemented in seven Tanzanian cities during the 1970s and 1980s, half of which provided infrastructure in previously unpopulated areas (de novo neighborhoods), while the other half upgraded squatter settlements. Using satellite images and surveys from the 2010s, we find that de novo neighborhoods developed better housing than adjacent residential areas (control areas) that were also initially unpopulated. Specifically, de novo neighborhood are more orderly and their buildings have larger footprint areas and are more likely to have multiple stories, as well as connections to electricity and water, basic sanitation and access to roads. And though de novo neighborhoods generally attracted better educated residents than control areas, the educational difference is too small to account for the large difference in residential quality that we find. While we have no natural counterfactual for the upgrading areas, descriptive evidence suggests that they are if anything worse than the control areas.

Abstract

We construct a new monthly dataset for UK government debt over the period 1694 to 2017 based on price and quantity data for each individual bond issued. This enables us to examine long run fiscal sustainability using the theoretically  relevant variable of the market value of debt, and investigate the historical importance of debt management. We find the general implications of the tax smoothing literature are replicated in our data, especially around financing wars, although we find major shifts over time in how fiscal sustainability is achieved. Before the 20th century, governments continued to pay bond holders a high rate of return and achieved sustainability through running fiscal surpluses but since then governments have relied on low growth adjusted real interest rates. The optimal debt management literature tends to favour the use of long bonds but we find the government would have been better off over the 20th century issuing short bonds. The contrast with the literature occurs because of an upward sloping yield curve and long bonds rarely providing fiscal insurance. This is particularly true during periods of financial crises when falling interest rates lead to sharp rises in the price of long bonds, making them an expensive form of finance. We examine the robustness of our conclusions to liquidity e¤ects, rollover risks, buyback operations and leverage. In general, these do suggest a greater role for long bonds but do not overturn an issuance strategy based mainly on short term bonds.

The adoption as policy models by central banks of representative agent New Keynesian dynamic stochastic general equilibrium models has been widely criticised, including for their simplistic micro-foundations. At the Bank of England, the previous generation of policy models is seen in its 1999 medium-term macro model (MTMM). Instead of improving that model to correct its considerable flaws, many shared by other non-DSGE policy models such as the Federal Reserve’s FRB/US, it was replaced in 2004 by the DSGE-based BEQM. Though this clearly failed during and after the global financial crisis, it was replaced in 2011 by the DSGE COMPASS, complemented by a ‘suite of models’. We provide a general critique of DSGE models for explaining, forecasting and policy analyses at central banks, and suggest new directions for improving current empirical macroeconomic models based on empirical modelling broadly consistent with better theory, rather than seeking to impose simplistic and unrealistic theory.

Our ability to adapt to extreme weather is increasingly relevant as the frequency and intensity of these events alters due to climate change. It is important to understand the effectiveness of adaptation given the uncertainty associated with future climate events. However, there has been little analysis of short-term adaptation efforts. We propose a novel approach of using errors from hurricane forecasts to evaluate short-term hurricane damage mitigation efforts. We construct a statistical model of damages for all hurricanes to strike the continental United States since 1955. While we allow for many possible drivers of damages, using model selection methods we find that a small subset explains most of the variation. We also find evidence supporting short-term adaptation effects prior to a hurricane landfall. Our results show that the 67 percent improvement in hurricane forecasts over the past 60 years is associated with damages being 16-63 percent lower than they otherwise would have been. Accounting for outlying observations narrows this range to 16-24 percent.

The paper measures real wages in St Petersburg, Moscow, and Kursk between 1853 and 1937 and compares them to real wages in Boston, Manchester, Bombay, and Cairo. Russian living standards grew little between 1853 and 1913 and were like Egypt and India. Wages in the UK and USA were 2.5 - 5 times greater. Real wages in Russia almost doubled between 1913 and 1928. When seen in a Russian perspective, this looks like a big advance; when seen internationally, it is much less so. Real wages dropped to their pre-War level between 1928 and 1937 during the industrialization drive.

We apply a classical economic categorization of preferences to identify the motivations of dual-users of electronic and traditional cigarettes. The responses of 2,406 U.S. adults (including 413 dual-users) in 2015 were collected using a novel online survey along with a follow-up in 2016 of 143 of these adults (68 dual-users). A sizeable minority of 37% of dual-users reported viewing electronic and conventional cigarettes primarily as complements. Of those who had never smoked or used electronic cigarettes, only 27% thought the complementarity motive would be primary. Dual-user motivations were associated with quit-attempt, cessation methods, gender and age. One year on, there was a positive relationship between the level of complementarity in the dual-user’s motives and their change in self-reported cigarette consumption. It is concluded that the application of a canonical economic classification of preferences may reveal important heterogeneities among the dual-user population.

Abstract

The paper synthesizes and develops the welfare analysis of regulating relative prices, for example price differences, of which banning price discrimination is a special case. Welfare results are derived directly by convexity arguments using functions of welfare levels. The method is also used to obtain results about e¤ects on consumer surplus.

Abstract

We propose a general framework for estimating the likelihood of default by central counterparties (CCP) in derivatives markets. Unlike conventional stress testing approaches, which estimate the ability of a CCP to withstand nonpayment by its two largest counterparties, we study the direct and indirect effects of nonpayment by members and/or their clients through the full network of exposures. We illustrate the approach for the credit default swaps (CDS) market under shocks that are similar in magnitude to the Federal Reserve's 2015 CCAR trading book shock. The analysis indicates that the main U.S. CCP for this market (ICE Clear Credit) could be more vulnerable than conventional stress testing approaches suggest.

Abstract

The reasons for and underlying composition of government budget deficits are often disregarded both by the academic literature about the links between fiscal policy and interest rates and by the policy debate about fiscal sustainability. However, we show that, from the perspective of financial markets, not all budget deficits are created equal: bond markets do discriminate between deficits that are the result of higher government current spending and those that stem from higher government investment, penalising the former significantly more than the latter. To do so, we apply a reduced-form regression approach to a panel of 31 OECD economies from 1960 to 2014 with data from the European Commission on the decomposition of the government budget deficit into its current spending, investment spending and revenue components. Quantitatively, based on our preferred specifications, a higher deficit solely due to higher government investment would in fact decrease long-term government bond yields. These findings suggest that austerity policies should focus more on current spending than investment spending and that fiscal rules in individual countries and monetary unions should distinguish budget deficits that are the result of investment from those that are not.

In the past 15 years a ‘task-based’ literature has emerged, exploring the consequences of technological change on the labour market. This literature relies on a particular understanding of the capabilities of machines – known as the ‘ALM hypothesis’. However, this hypothesis has often led the literature to underestimate these capabilities. Tasks that were believed to be out of reach of automation can now be automated. In this paper I set out two distinct explanations for why these capabilities were underestimated – one that is explored in the recent literature and maintains the ALM hypothesis, and a new explanation that challenges it. I propose a new hypothesis that nests the ALM hypothesis as a special case.

Does adult stature capture conditions at birth or at some other stage in the growth cycle? Anthropometrics is lauded as a method for capturing net nutritional status over all the growing years. However, it is frequently assumed that conditions at birth were most influential. Was this true for historical populations? This paper examines the heights of Belgian men born between 1800-76 to tease apart which moments of growth were most sensitive to disruption and reflected in final heights. It exploits two proximate crises in 1846-49 and 1853-56 as shocks that permit age effects to be revealed. These are affirmed through a study of food prices and death rates. Both approaches suggest a shift of the critical moment away from the first few years of life and towards the adolescent growth spurt as the most influential on terminal stature. Furthermore, just as height is accumulated over the growing years, conditions influencing growth need to be understood cumulatively. Economic conditions at the time of birth were not explanatory, but their collective effects from ages 11 to 18 years were strongly influential. Then, both health and nutrition mattered, in shifting degrees. Teenagers, not toddlers, should be our guides to the past.

Abstract

In the past 15 years a ‘task-based’ literature has emerged, exploring the consequences of technological change on the labour market. This literature supports an optimistic view about the threat of automation. In this paper I build a task-based model based on different reasoning about how machines operate. This leads to a far more pessimistic account of the prospects for labour. In a static model, increasingly capable machines drive down relative wages and the labour share of income and force labour to specialise in a shrinking set of tasks. In a dynamic version of the model, labour is driven out the economy at an endogenously determined rate, forced to specialise in a shrinking set of types of tasks, and wages steadily decline to zero. In the limit, labour is fully immiserated and ‘technological unemployment’ follows.

Abstract

Using annual data from the thirteenth century to the present, we show that improved long run economic performance has occurred primarily through a decline in the rate and frequency of shrinking, rather than through an increase in the rate of growing. Indeed, as economic performance has improved over time, the short run rate of growing has typically declined rather than increased. Most analysis of the process of economic development has hitherto focused on increasing the rate of growing. Here, we focus on understanding the forces making for a reduction in the rate of shrinking, drawing a distinction between proximate and ultimate factors. The main proximate factors considered are (1) structural change (2) technological change (3) demographic change and (4) the changing incidence of warfare. We conclude with a consideration of institutional change as the key ultimate factor behind the reduction in shrinking.

Abstract

Japanese GDP per capita grew at an annual rate of 0.08 per cent between 730 and 1874, but the growth was episodic, with the increase in per capita income concentrated in two
periods, 1450-1600 and after 1721, interspersed with periods of stable per capita income. There is a similarity here with the growth pattern of Britain. The first countries to achieve modern economic growth at opposite ends of Eurasia thus shared the experience of an early end to growth reversals. However, Japan started at a lower level than Britain and grew more slowly until the Meiji Restoration.

Abstract

Chinese GDP per capita fluctuated at a high level during the Northern Song and Ming dynasties before trending downwards during the Qing dynasty. China led the world in living standards during the Northern Song dynasty, but had fallen behind Italy by 1300. At this stage, it is possible that parts of China were still on a par with the richest parts of Europe, but by 1750 the gap was too large to be bridged by regional variation within China and the Great Divergence had already begun before the Industrial Revolution.

Abstract

This paper develops a change-point VAR model that isolates four major macroeconomic regimes in the US since the 1960s. The model identi es shocks to demand, supply, monetary
policy, and spread yield using restrictions from a general equilibrium model. The analysis discloses important changes to the statistical properties of key macroeconomic variables and their responses to the identi ed shocks. During the crisis period, spread shocks became more important for movements in unemployment and in ation. A counterfactual exercise evaluates the importance of lower bond-yield spread during the crises and suggests that the Fed's largescale asset purchases helped lower the unemployment rate by about 0.6 percentage points, while boosting in ation by about 1 percentage point.

Abstract

This paper discusses and documents a new dataset of real wages for unskilled, semi-skilled, and relatively skilled labour in Argentina, Brazil, Chile, Colombia, Mexico, and Venezuela (LA-6) over the period 1900-2011. Three interrelated aspects are examined: the wage growth record associated with periods dominated by a particular development strategy; wage convergence across the LA-6; and changes in wage skill premiums and their links with fundamentals. The key findings are: i) the region’s unskilled wage rose by 147% in the period compared to rises of 243% in the average wage and 440% in income per worker (including both property and labour income); ii) there is a limited process of wage convergence across the LA-6; and weak persistence in the country hierarchy; iii) skill premiums tended to peak during the middle decades of the 20th century, coinciding with the acceleration of industrialisation and the timing of the demographic transition. Movements in the terms of trade are broadly associated with both fluctuations and trends in wage premiums, though the direction of the link is country and time specific.

Abstract

How do product variety and quality affect the aggregate price bias? We develop a general equilibrium model that accounts for the joint interaction of product quality and variety. Our findings show that the aggregate price bias is pro-cyclical and the contribution of product variety is persistent whereas the contribution of product quality becomes counter-cyclical in the medium to long run. We show that accounting for product quality and variety has critical implications on the measure of cyclical fluctuations. Measurements of cyclical fluctuations derived using the consumption deflator, which abstracts from changes in product quality and variety, underestimate the variables' true volatility.
