The Effect of Foreign Competition on Forecasting Bias

The Review of Economics and Statistics 2006 88(1), 61-68
This paper studies the effect of foreign competition on the extent of forecasting bias. I focus on two biases often described in the behavioral economics literature: overoptimism and excessive belief in trends. Using data from firm-level surveys in five African countries, I show that firms that do not face foreign competition generate forecasts of sales growth that have greater trend and optimism biases than firms that have foreign competitors. I further provide evidence that these erroneous forecasts have real effects on firms' inventory management.

Estimating the Value of Political Connections

American Economic Review 2001 91(4), 1095-1102
As the Indonesian economy went into a downward spiral in the latter half of 1997, there was much speculation and debate as to the reasons behind the sudden decline. Most explanations gave at least some role to investor panic, which had led to a massive outflow of foreign capital. At the root of this hysteria, however, were concerns that the capital that had flowed into Indonesia and elsewhere in Southeast Asia had not been used for productive investments. Much of this discussion focused on the role of political connections in driving investment. The claim was that in Southeast Asia, political connectedness, rather than fundamentals such as productivity, was the primary determinant of profitability and that this had led to distorted investment decisions. Obviously, the degree to which this type of problem was truly responsible for the Asian collapse depends very much on the extent to which connectedness really was a primary determinant of firm value. In making the argument that this was in fact the case, anecdotes about the business dealings of President Suharto’s children were often cited as evidence. Such stories suggest that the value of some firms may have been highly dependent on their political connections. However, investigations in this area have not progressed beyond the level of case study and anecdote. That is, there has been no attempt to estimate the degree to which firms rely on connections for their profitability. There are numerous difficulties that would

Does Competition Encourage Credit Provision? Evidence from African Trade Credit Relationships

The Review of Economics and Statistics 2004 86(1), 345-352
Previous work has claimed that monopoly power facilitates the provision of credit, because monopolists are better able to enforce payment. Here, we argue that if relationship-specific investments are required by borrowers to establish creditworthiness, monopoly power may reduce credit provision because holdup problems ex post will deter borrowers from investing in establishing creditworthiness. Empirically, we examine the relationship between monopoly power and credit provision, using data on the supply relationships of firms in five African countries. Consistent with the up-front investment story, we find that monopoly power is negatively associated with credit provision, and that this correlation is stronger in older supplier relationships. Because the data include several observations per firm, we are able to utilize firm fixed effects, thus netting out unobserved firm characteristics that may have been driving results in earlier studies.

Tax Rates and Tax Evasion: Evidence from “Missing Imports” in China

Journal of Political Economy 2004 112(2), 471-496 open access
Tax evasion, by its very nature, is difficult to observe. We quantify the effects of tax rates on tax evasion by examining the relationship in China between the tariff schedule and the "evasion gap," which we define as the difference between Hong Kong's reported exports to China at the product level and China's reported imports from Hong Kong. Our results imply that a one-percentage-point increase in the tax rate is associated with a 3 percent increase in evasion. Furthermore, the evasion gap is negatively correlated with tax rates on closely related products, suggesting that evasion takes place partly through misclassification of imports from higher-taxed categories to lower-taxed ones, in addition to underreporting the value of imports.

Do Stronger Intellectual Property Rights Increase International Technology Transfer? Empirical Evidence from U. S. Firm-Level Panel Data

Quarterly Journal of Economics 2006 121(1), 321-349
This paper examines how technology transfer within U. S. multinational firms changes in response to a series of IPR reforms undertaken by sixteen countries over the 1982–1999 period. Analysis of detailed firm-level data reveals that royalty payments for technology transferred to affiliates increase at the time of reforms, as do affiliate R&D expenditures and total levels of foreign patent applications. Increases in royalty payments and R&D expenditures are concentrated among affiliates of parent companies that use U. S. patents extensively prior to reform and are therefore expected to value IPR reform most. For this set of affiliates, increases in royalty payments exceed 30 percent.

The Mortality Cost of Political Connections

Review of Economic Studies 2015 82(4), 1346-1382 open access
We study the relationship between the political connections of Chinese firms and workplace fatalities. In our preferred specification we find that the worker death rate for connected companies is two to three times that of unconnected firms (depending on the sample employed), a pattern that holds for within-firm estimations. The connections-mortality relationship is attenuated in provinces where safety regulators' promotion is contingent on meeting safety targets. In the absence of fatalities, connected firms receive fewer reports of major violations for safety compliance, whereas in years of fatal accidents the rate of reported violations is identical. Moreover, fatal accidents produce negative returns at connected companies and are associated with the subsequent departure of well-connected executives. These results provide suggestive evidence that connections enable firms to avoid (potentially costly) compliance measures, rather than using connections to avoid regulatory response after accidents occur. Our findings emphasize the social costs of political connections, and suggest that appropriate regulatory incentives may be useful in mitigating these costs.

Outsourcing Tariff Evasion: A New Explanation for Entrepôt Trade

The Review of Economics and Statistics 2008 90(3), 587-592 open access
Traditional explanations for indirect trade through an entrept focus on savings in transport costs and the role of specialized agents in processing and distribution. We provide an alternative perspective based on the potential for entrepts to facilitate tariff evasion. Using data on direct exports to mainland China and indirect exports via Hong Kong SAR, we find that the indirect export rate rises with the Chinese tariff rate, despite the absence of any legal tax advantage to sending goods via Hong Kong SAR. We present several robustness tests to rule out plausible alternative hypotheses based on existing explanations for entrept trade.

Cultural Proximity and Loan Outcomes

American Economic Review 2017 107(2), 457-492 open access
We present evidence that cultural proximity (shared codes, beliefs, ethnicity) between lenders and borrowers increases the quantity of credit and reduces default. We identify in-group lending using dyadic data on religion and caste for officers and borrowers from an Indian bank, and a rotation policy that induces exogenous matching between them. Having an in-group officer increases credit access and loan size dispersion, reduces collateral requirements, and induces better repayment even after the in-group officer leaves. We consider a range of explanations and suggest that the findings are most easily explained by cultural proximity serving to mitigate information frictions in lending.
