This paper assesses the effects of capital gains taxes on investment in the Republic of Korea (hereafter, Korea), where capital gains tax rates vary at the firm level by firm size. Following a reform in 2014, firms with a tax cut increased investment by 34 log points and issued more equity by 9 cents per dollar of lagged revenue, relative to unaffected firms. Additionally, the effects were larger for firms that appeared more cash constrained or went public after the reform. Taken together, these findings are consistent with the “traditional view” predicting that lower payout taxes spur equity-financed investment by increasing marginal returns on investment. (JEL D25, G31, G32, H25, H32, L25)

Smallholder farming in many developing countries is characterized by low productivity and low-quality output. Low quality limits the price farmers can command and their potential income. We conduct a series of experiments among maize farmers in Uganda to shed light on the barriers to quality upgrading and to study its potential. We find that the causal return to quality is zero. Providing access to a market where quality is paid a market premium led to an increase in farm productivity and income from farming. Our findings reveal the importance of demand-side constraints in limiting rural income and productivity growth. (JEL C93, L14, L15, L22, O13, Q12, Q13)

We analyze the effects of Mafia infiltration in the legal economy. Combining information from investigative records with panel data on firms’ governance and balance sheets, we build an indicator of infiltration in firms located in an area with no tradition of Mafia. We show that Mafia targets young and less efficient firms and that infiltration generates a significant rise in firms’ revenues, with no proportionate growth in production inputs and a deterioration of the firm’s financial situation leading to market exit. These findings are consistent with a story of predatory behavior in which infiltration is used for money laundering or rent extraction. (JEL D22, G32, G34, K42, L25)

Can information and communication technologies help citizens monitor their elections? We analyze a large-scale field experiment designed to answer this question in Colombia. We leveraged Facebook advertisements sent to over 4 million potential voters to encourage citizen reporting of electoral irregularities. We also cross-randomized whether candidates were informed about the campaign in a subset of municipalities. Total reports, and evidence-backed ones, experienced a large increase. Across a wide array of measures, electoral irregularities decreased. Finally, the reporting campaign reduced the vote share of candidates dependent on irregularities. This light-touch intervention is more cost-effective than monitoring efforts traditionally used by policymakers. (JEL C93, D12, D72, D83, O17)

This paper quantifies employer market power in US manufacturing and how it has changed over time. Using administrative data, we estimate plant-level markdowns—the ratio between a plant’s marginal revenue product of labor and its wage. We find most manufacturing plants operate in a monopsonistic environment, with an average markdown of 1.53, implying a worker earning only 65 cents on the marginal dollar generated. To investigate long-term trends for the entire sector, we propose a novel, theoretically grounded measure for the aggregate markdown. We find that it decreased between the late 1970s and the early 2000s, but has been sharply increasing since. (JEL J24, J31, J38, J42, L13, L60)

I briefly review the emergence of “ design-based” research methods in labor economics in the 1980s and early 1990s. These methods were seen as a partial solution to the problems of credible inference identified by Ashenfelter (1974), Leamer (1978), Hendry (1980), and others. Designed-based studies typically use a simplified one-equation model of the outcome of interest—in contrast to model-based studies that specify a data generating process for all factors determining the outcome. I discuss some of the strengths and weaknesses of the design-based approach and the value of such research in the field. (JEL C20, J01, J24, J31, J38, J51, J53)

This paper shows how deportation policies can backfire by disseminating not only ideas between countries but also criminal networks, spreading gangs, in this case, across El Salvador, and spurring migration back to the United States. In 1996, the US Illegal Immigration Responsibility Act increased the number of criminal deportations. In particular, the members of large Salvadoran gangs developed in Los Angeles were sent back to El Salvador. Using variation in criminal deportations over time and across cohorts, combined with geographical variation in US gangs’ location, I find that these deportations led to an increase in homicide rates and gang activity, as well as an increase in gang recruitment and migration of children.

Two players bargain over a single indivisible good and a transfer, with one-sided incomplete information about preferences. Both players can offer arbitrary mechanisms to determine the allocation. We show that there is a unique perfect Bayesian equilibrium outcome. In the equilibrium, one of the players proposes a menu that is optimal for the uninformed player among all menus, such that each type of the informed player receives at least her payoff under complete information. The optimal menu can be implemented with at most three allocations. Under a natural assumption on the uninformed player’s beliefs, the optimal menu coincides with the Myerson’s neutral solution to the bargaining problem in this environment. (JEL C78, D82, D83)

Concentration-based thresholds for horizontal mergers, such as those in the US Horizontal Merger Guidelines, play a central role in merger analysis but their basis remains unclear. We show that there is both a theoretical and an empirical basis for focusing solely on the change in concentration, and ignoring its level, in screening mergers for whether their unilateral price effects will harm consumers. We also argue that current threshold levels likely are too lax, unless one expects efficiency gains of 5 percent or greater, or other factors such as entry and product repositioning to significantly constrain the exercise of market power postmerger.
