| 報告 | Tomoki Fujii (Singapore Management University) Do Natural Disasters Cause Domestic Violence?: A study of the 2015 Nepal earthquake (joint work with Arpita Khanna) [Paper] |
| Abstract | This study estimates the impact of exposure to the 2015 Nepal Earthquake on intimate partner violence with two rounds of Demographic and Health Surveys data. Using differences-in-differences estimation, we find that exposure to the earthquake lead to a statistically and economically significant increase in intimate partner violence in the urban areas but not in the rural areas. This is possibly due to an increase in the stress felt by the victims. We also offer some evidence that the impact heterogeneity between the urban and rural areas is attributable to the differences in the reconstruction processes and assistance provided. |

| 報告 | Cheng Chen (Clemson University) Uncertainty, Imperfect Information, and Expectation Formation over the Firm's Life Cycle
|
| Abstract |
Using a long-panel data set of Japanese firms that contains firm-level sales forecasts, we provide evidence on firm-level uncertainty and imperfect information over their life cycles. We find that firms make nonnegligible and positively correlated forecast errors. However, they make more precise forecasts and less correlated forecast errors when they become more experienced. We then build a model of heterogeneous firms with endogenous entry and exit where firms gradually learn about their demand by using a noisy signal. We present our novel approach to cleanly isolate the learning mechanism from other mechanisms by using expectations data over time. We combine the model with our data to perform a nonparametric decomposition of the age-declining forecast errors and find that learning accounts for between 20% to 40% of the overall decline in forecast errors observed in our data. Our model shows that, within the context of our cross-regional data, productivity gains from removing information frictions range from 6% to 12%.

| 報告 | Anna Ignatenko(Ludwig-Maximilians University of Munich) Countervailing Power of Firms in International Trade [Paper]
|
| Abstract | Price variation across buyers within product categories is commonly explained by quality variation in international trade. Using uniquely detailed product descriptions, I control for quality and study market-power mechanisms of price variation across buyers. I develop a model of trade, in which buyers and sellers differ in productivity and can have market power to set prices. It predicts differential patterns of price variation with buyer productivity under oligopoly, oligopsony and bilateral bargaining in a standard international trade environment. Testing these predictions, I find that, in most markets, price variation is consistent with price discrimination by oligopolistic sellers charging lower mark-ups to more productive buyers. I identify the role of buyer’s outside options in this result separately from scale economies, transfer pricing and bargaining ability. These findings imply large productive firms benefit more from trade liberalization due to their ability to further reduce input prices by threatening to use alternative suppliers. |

| Abstract | We consider the efficiency of market entry in single- and two-sector closed-economy versions of the Melitz-Ottavanio (MO) model, where differently from the MO model our two-sector model does not involve an outside good. For each model version, we assess whether the market level of entry is efficient relative to the second-best setting in which the planner can control only the level of entry. Focusing on entry levels that induce selection, we show that the market level of entry is efficient in the single-sector model. For a two-sector MO model without an outside good, we show that the welfare results are exactly similar to those in the one-sector model
when the two sectors are symmetric. When the two sectors are asymmetric and the level of asymmetry is sufficiently small, we identify a perturbation indicating a sense in which the market level of entry into the ìhigh-demandîsector is excessive. This intersectoral misallocation occurs at the market equilibrium even though endogenous average markups are equal across sectors. We also show how the outcomes induced by the planner ís direct choice of entry levels alternatively can be induced through the appropriate choice of entry tax/subsidy policies.

| 報告 | Joel Rodrigue (Vanderbilt University) Exporting and Investment under Credit Constraints" [Paper] |
| Abstract | We examine the relationship between firms’ performance and credit constraints affecting export market entry. The existing research assumes that variation in firms’ financial conditions identifies credit constraints. A critical assumption is that financial conditions do not affect real outcomes (performance, exporting, or investment). To relax this assumption, we focus on the direct effect of firms’ fundamentals and financial conditions on firms’ performance. This approach distinguishes between firms that choose not to export because it is unprofitable from firms that do not export because of binding credit constraints. Our empirical specification allows firms’ characteristics to enter both the selection into exporting and return from exporting regressions. The leverage response heterogeneity identifies the presence of credit constraints. Using administrative Canadian firm-level data, our findings show that new exporters (a) increase their productivity, (b) raise their leverage ratio and (c) increase investment. We estimate that 48 percent of Canadian manufacturers face binding credit constraints when deciding whether to enter export markets. Alleviating these constraints would increase aggregate productivity by 0.97–1.04 percentage points. |
