  We quantify the importance of imperfect competition in the US labor market by estimating the size of labor market rents earned by American firms and workers. We construct a matched employeremployee panel dataset by combining the universe of US business and worker tax records for the period 2001–2015. Using this panel data, we identify and estimate an equilibrium model of the labor market with two-sided heterogeneity where workers view firms as imperfect substitutes because of heterogeneous preferences over nonwage job characteristics. The model allows us to draw inference about imperfect competition, worker sorting, compensating differentials, and rent sharing.

  We examine how the adoption of information communication technology affects bilateral trade. The context is a public program in Norway that rolled out broadband access points leading to plausibly exogenous variation in the availability and adoption of broadband by firms. We find that broadband makes trade patterns more sensitive to distance and economic size. These results are consistent with a model of trade with variable elasticity of demand. The model predicts that adoption of a technology that lowers information frictions enlarges the choice set of exporters and importers. This makes demand more elastic with respect to trade costs and thus distance.

  The synthetic control (SC) method is widely used in comparative case studies to adjust for differences in pretreatment characteristics. SC limits extrapolation bias at the potential expense of interpolation bias, whereas traditional matching estimators have the opposite properties. This complementarity motives us to propose a matching and synthetic control (or MASC) estimator as a model averaging estimator that combines the standard SC and matching estimators. We show how to use a rolling-origin cross-validation procedure to train the MASC to resolve tradeoffs between interpolation and extrapolation bias. We use a series of empirically based placebo and Monte Carlo simulations to shed light on when the SC, matching, MASC and penalized SC estimators do (and do not) perform well. Then, we apply these estimators to examine the economic costs of conflicts in the context of Spain.

  Empirical researchers often combine multiple instrumental variables (IVs) for a single treatment using two-stage least squares (2SLS). When treatment effects are heterogeneous, a common justification for including multiple IVs is that the 2SLS estimand can be given a causal interpretation as a positively weighted average of local average treatment effects (LATEs). This justification requires the well-known monotonicity condition. However, we show that with more than one instrument, this condition can only be satisfied if choice behavior is effectively homogeneous. Based on this finding, we consider the use of multiple IVs under a weaker, partial monotonicity condition. We characterize empirically verifiable sufficient and necessary conditions for the 2SLS estimand to be a positively weighted average of LATEs under partial monotonicity. We apply these results to an empirical analysis of the returns to college with multiple instruments. We show that the standard monotonicity condition is at odds with the data. Nevertheless, our empirical checks reveal that the 2SLS estimate retains a causal interpretation as a positively weighted average of the effects of college attendance among complier groups.

  We study the impacts of a major reform to vocational secondary education that aimed to move beyond the trade-off between providing occupational skills and closing off academic opportunities. Norway’s Reform 94 integrated more general education into the vocational track, offered vocational students a pathway to college, and increased access to apprenticeships. We identify reform impacts through a difference-in-discontinuity research design applied to linked population registries. The reform substantially increased initial vocational enrollment, but with divergent consequences by gender. Overall, the reform succeeded at improving social mobility, particularly for disadvantaged men, but it somewhat exacerbated the gender gap in adult earnings.

  We examine how many and what kind of firms ultimately rely on foreign inputs, sell to foreign markets, and are affected by trade shocks. To capture that firms can trade indirectly by buying from or selling to domestic firms that import or export, we use Belgian data with information on both domestic firm-to-firm sales and foreign trade transactions. We find that most firms use a lot of foreign inputs, but only a small number of firms show that dependence through direct imports. While direct exporters are rare, a majority of firms are indirectly exporting. In most firms, however, indirect export is quantitatively modest, and sales at home are the key source of revenue. We show that what matters for the transmission of foreign demand shocks to a firm’s revenue is how much the firm ultimately sells to foreign markets, not whether these sales are from direct or indirect export.

  We show that family background matters significantly for children’s accumulation of wealth and investor behavior as adults, even when removing the genetic connection between children and the parents raising them. The analysis is made possible by linking Korean-born children who were adopted at infancy by Norwegian parents to a population panel data set with detailed information on wealth and socio-economic characteristics. The mechanism by which these Korean- Norwegian adoptees were assigned to adoptive families is known and effectively random. This mechanism allows us to estimate the causal effects from an adoptee being raised in one type of family versus another.

  A major difficulty faced by researchers who want to study the consumption and savings behavior of households is the lack of reliable panel data on household expenditures. One possibility is to use surveys that follow the same households over time, but such data are rare and they typically have small sample sizes and face significant measurement issues. An alternative approach is to use the accounting identity that total household spending is equal to income plus capital gains minus the change in wealth over the period. The goal of this paper is to examine the advantages and difficulties of using this accounting identity to construct a population panel data with information on household expenditure. To derive such measures of consumption expenditure, we combine several data sources from Norway over the period 1994–2014.

  There is no evaluation of the consequences of Disability Insurance (DI) receipt that captures the effects on households' net income and consumption expenditure, family labor supply, or benefits from other programs. Combining detailed register data from Norway with an instrumental variables approach based on random assignment to appellant judges, we comprehensively assess how DI receipt affects these understudied outcomes. To consider the welfare implications of the findings from this instrumental variables approach, we estimate a dynamic model of household behavior that translates employment, reapplication, and savings decisions into revealed preferences for leisure and consumption. The model-based results suggest that on average, the willingness to pay for DI receipt is positive and sizable. Because spousal labor supply strongly buffers the household income and consumption effects of DI allowances, the estimated willingness to pay for DI receipt is smaller for married than single applicants.

  Using a random judge design and panel data from Norway, we estimate that imprisonment discourages further criminal behavior, with reoffense probabilities falling by 29 percentage points and criminal charges dropping by 11 over a 5-year period. Ordinary least squares mistakenly reaches the opposite conclusion. The decline is driven by individuals not working prior to incarceration; these individuals increase participation in employment programs and raise their future employment and earnings. Previously employed individuals experience lasting negative employment effects. These findings demonstrate that time spent in prison with a focus on rehabilitation can be preventive for a large segment of the criminal population.

  We use data from Denmark, Germany, Norway, the United Kingdom, and the United States to document the degree of educational assortative mating, how it evolves over time, and the extent to which it differs between countries. This descriptive analysis motivates and guides a decomposition analysis in which we quantify the contribution of various factors to the distribution of household income. We find that assortative mating accounts for a nonnegligible part of the cross-sectional inequality in household income in each country. However, changes in assortative mating over time barely move the time trends in household income inequality.

  In this comment on their paper, we first briefly summarize in Section 2 the most general framework for the problem that they consider. We then specialize their framework so as to highlight a connection (already noted by the authors themselves) to the multiple testing literature. By doing so, we facilitate a comparison in Section 3 with a closely related multiple testing problem considered in Mogstad, Romano, Shaikh, and Wilhelm(2020). Throughout our discussion, in addition to some key distinctions in the a symptotic framework employed in each paper, we emphasize two additional differences: differences in the choice of error rate for each multiple testing problem and differences in the way in which the θiare treated. In Section 4, we discuss the practical importance of these differences. To further emphasize what we feel are important distinctions in the interpretation of the results provided by the two methods, we cast this discussion in the context of the aforementioned teacher value-added example

  This paper reviews the literature on intergenerational mobility. While our review is centered around the large empirical literature on this topic, we also give a brief discussion of some of the relevant theory. We consider three strands of the empirical literature. First, we discuss how to measure intergenerational persistence in various socio-economic outcomes. We discuss both measurement challenges and some notable findings. We then turn to quantifying the importance of family environment and genetic factors for children's outcomes. We describe the pros and cons of various approaches as well as key findings. The third strand is concerned with drawing causal inferences about how children's outcomes are affected by specific features of their family environment. We discuss a wide range of environmental features, including the neighborhoods in which children grow up. We critically assess what conclusions one may and may not draw from certain celebrated studies of neighborhoods and intergenerational mobility.

  We quantify the importance of imperfect competition in the US construction industry by estimating the size of rents earned by American firms and workers. To obtain a comprehensive measure of the total rents and to understand its sources, we take into account that rents may arise due to markdown of wages in the labor market, or markup of prices in the product market, or both. Our analyses combine the universe of US business and worker tax records with newly collected records from US procurement auctions. We use this data to identify and estimate a model where construction firms compete with one another for projects in the product market and for workers in the labor market. The firms may participate both in the private market and in government projects procured through auctions. We find evidence of considerable wage- and price-setting power. This imperfect competition creates sizable rents, three-fourths of which is captured by the firms. The incentives of firms to mark down wages and reduce employment due to wage-setting power are attenuated by their price-setting power in the product market.

  Do employees benefit from worker representation on corporate boards? Economists and policymakers are keenly interested in this question – especially lately, as worker representation is widely promoted as an important way to ensure the interests and views of the workers. To investigate this question, we apply a variety of research designs to administrative data from Norway. We find that a worker is paid more and faces less earnings risk if she gets a job in a firm with worker representation on the corporate board. However, these gains in wages and declines in earnings risk are not caused by worker representation per se. Instead, the wage premium and reduced earnings risk reflect that firms with worker representation are likely to be larger and unionized, and that larger and unionized firms tend to both pay a premium and provide better insurance to workers against fluctuations in firm performance. Conditional on the firm’s size and unionization rate, worker representation has little if any effect. Taken together, these findings suggest that while workers may indeed benefit from being employed in firms with worker representation, they would not benefit from legislation mandating worker representation on corporate boards.

  It is often desired to rank different populations according to the value of some feature of each population. For example, it may be desired to rank neighborhoods according to some measure of intergenerational mobility or countries according to some measure of academic achievement. These rankings are invariably computed using estimates rather than the true values of these features. As a result, there may be considerable uncertainty concerning the rank of each population. In this paper, we consider the problem of accounting for such uncertainty by constructing confidence sets for the rank of each population. We consider both the problem of constructing marginal confidence sets for the rank of a particular population as well as simultaneous confidence sets for the ranks of all populations. We show how to construct such confidence sets under weak assumptions. An important feature of all of our constructions is that they remain computationally feasible even when the number of populations is very large. We apply our theoretical results to re-examine the rankings of both neighborhoods in the United States in terms of intergenerational mobility and developed countries in terms of academic achievement. The conclusions about which countries do best and worst at reading, math, and science are fairly robust to accounting for uncertainty. By comparison, several celebrated findings about intergenerational mobility in the United states are not robust to taking uncertainty into account.

  High school vocational education has a controversial history in the United States, largely due to a perceived tradeoff between teaching readily deployable occupational skills versus shunting mostly disadvantaged students away from the educational and career flexibility afforded by general academic courses. We study the effects of a nationwide high school reform in Norway that aimed to move beyond this tradeoff. Reform 94, implemented in one step in the fall of 1994, integrated more general education into the vocational track, offered vocational students a pathway to college through a supplementary semester of academic courses, and sought to improve the quality of the vocational track through greater access to apprenticeships. We identify the impacts of the reform through a difference-in-discontinuity research design, comparing students born just before and after the reform’s birthdate eligibility cutoff to students born around the same cutoff in placebo years. Linking multiple administrative registries covering the entire Norwegian population, we find that the reform substantially increased initial enrollment in the vocational track, but with different subsequent outcomes for different groups. More men complete the vocational track at the expense of academic diplomas, but this has no detectable impact on college-going and leads to reduced criminal activity and higher earnings in adulthood, especially among disadvantaged men. For disadvantaged women, the initial surge in vocational enrollment leads to fewer high school dropouts and more vocational degrees with the college-prep supplement, and hence an increase in the share of college-eligible women; however, this translates into only small and insignificant increases in college completion and adult earnings. We show that men overwhelmingly pursue vocational education in higher-paying skilled trade fields, while women almost exclusively pursue vocational education in lower-paying service-based fields, which helps in interpreting some of these results. Overall, the reform succeeded at improving social mobility, particularly among men, but it somewhat exacerbated the gender gap in adult earnings.

  Empirical researchers often combine multiple instruments for a single treatment using two stage least squares (2SLS). When treatment effects are heterogeneous, a common justification for including multiple instruments is that the 2SLS estimand can still be interpreted as a positivelyweighted average of local average treatment effects (LATEs). This justification requires the wellknown monotonicity condition. However, we show that with more than one instrument, this condition can only be satisfied if choice behavior is effectively homogenous. Based on this finding, we consider the use of multiple instruments under a weaker, partial monotonicity condition. This condition is implied by standard choice theory and allows for richer heterogeneity. First, we show that the weaker partial monotonicity condition can still suffice for the 2SLS estimand to be a positively-weighted average of LATEs. We characterize a simple sufficient and necessary condition that empirical researchers can check to ensure positive weights. Second, we develop a general method for using multiple instruments to identify a wide range of causal parameters other than LATEs. The method allows researchers to combine multiple instruments to obtain more informative empirical conclusions than one would obtain by using each instrument separately.

  The primary goal of our paper is to quantify the importance of imperfect competition in the U.S. labor market by estimating the size of rents earned by American firms and workers from ongoing employment relationships. To this end, we construct a matched employer-employee panel data set by combining the universe of U.S. business and worker tax records for the period 2001-2015. We describe several important features of the U.S. labor market, including the size of firm-specific wage premiums, the sorting of workers to firms, the production complementarities between high ability workers and productive firms, and the pass-through of firm and market shocks to workers' wages. Guided by these empirical results, we develop, identify and estimate an equilibrium model of the labor market with two-sided heterogeneity where workers view firms as imperfect substitutes because of heterogeneous preferences over non-wage job characteristics. The model allows us to draw inference about imperfect competition, compensating differentials and rent sharing. We also use the model to quantify the relevance of non-wage job characteristics and imperfect competition for inequality and tax policy, to assess the economic determinants of worker sorting, and to offer a unifying explanation of key empirical features of the U.S. labor market.

  Almost one third of women worldwide report some form of physical or sexual violence by a partner in their lifetime, yet little is known about the mental health and well-being effects for either victims or their children. We study the costs associated with domestic violence (DV) in the context of Norway, where we can link offenders to victims and their children over time. Our difference-in-differences framework uses those who will be victimized in the future as controls. We find that a DV report involving the police is associated with large changes in the home environment, including marital dissolution and a corresponding decline in financial resources. A DV report increases mental health visits by 35% for victims and by 19% for their children in the year of the event, effects which taper off over time for the victim, but not for children. Victims also experience more doctor visits, lower employment, reduced earnings and a higher use of disability insurance while their children are more likely to receive child protective services and commit a crime. Using a complementary RD design, we find that a DV report results in declines both in children’s test scores and completion of the first year of high school.
