Exporters and the environment

This paper documents a relationship between international trade and environmental performance at the plant level. Using a panel of establishment‐level data from 1990–2006, I estimate the relationship between export orientation, import competition and pollution emissions. I find a robust relationship between international trade and pollution levels. Exporters emit 9% to 13% less after controlling for output, but there is significant heterogeneity across industries. Import competition is associated with the exit of the smallest, most pollution‐intensive plants. There is no evidence that this result is caused by polluting firms relocating to countries with low levels of environmental regulation and importing back into the US.     

Who Exports Better Quality Products to Smaller or More Distant Markets?

The role of across‐firm differences in product quality and firms' competitiveness in determining the spatial patterns of within‐product export unit values across destinations is examined in this paper. Using product level export data, it is shown that the average export unit value of a product shipped from the USA or Korea increases with distance and decreases with destination market's size. However, within‐product average unit values for products exported from China and India decrease with distance and increase with market size. To interpret these different spatial patterns of unit values across exporting countries, model of quality heterogeneity is developed in which firms differ in their workers' skill level and higher‐skilled workers show greater productivity in performing tasks that improve product quality. The model predicts that in relatively skill‐abundant countries, exporting firms specialize in high‐quality products using relatively cheap skilled labor, whereas, in relatively skill‐scarce countries, firms that produce lower‐quality products are more competitive.     

GOVERNMENT POLICY IN MONETARY ECONOMIES*

I study how the general and specific details of a micro‐founded monetary framework affect the determination of policy when the government has limited commitment. In the general framework, policy is determined by the interaction between the incentives to smooth distortion intertemporally and a time‐consistency problem. Resolving financial and trading frictions affects long‐run policy significantly. Policy response to fluctuations in productivity is quantitatively different across model variants, mainly due to the idiosyncratic behavior of the money demand. Other types of shocks, both transitory and permanent, affect policy in a similar manner across a variety of specifications.     

Informal Insurance Arrangements with Limited Commitment: Theory and Evidence from Village Economies

Recent work on consumption allocations in village economies finds that idiosyncratic variation in consumption is systematically related to idiosyncratic variation in income, thus rejecting the hypothesis of full risk-pooling. We attempt to explain these observations by adding limited commitment as an impediment to risk-pooling. We provide a general dynamic model and completely characterise efficient informal insurance arrangements constrained by limited commitment, and test the model using data from three Indian villages. We find that the model can fully explain the dynamic response of consumption to income, but that it fails to explain the distribution of consumption across households.     

Trade balance dynamics and exchange rates: In search of the J‐curve using a structural gravity approach

This paper uses a structural gravity approach, specifying currency movements as trade cost component to derive an empirical trade balance model, which incorporates multilateral resistance terms and accounts for the cross‐country variation in the exchange rate pass‐through into import and export prices. The model is estimated using quarterly bilateral trade flows between 47 countries over the period 2010Q1 to 2017Q2, disaggregated into 97 commodity groups. Our results support the existence of an “aggregate” J‐curve, pooled over commodity groups; at the same time they point to considerable heterogeneity in the trade balance dynamics across industries below the surface of aggregate data.     

Exporters in cross‐section: Direct versus intermediated trade

How do producers that export their goods directly differ from those that export through trade intermediaries? We take a standard model of trade with heterogeneous firms and add heterogeneity in quality to the usual heterogeneity in productivity. Modeling trade intermediaries as increasing marginal costs but decreasing fixed costs of exporting, we find that only firms with the highest quality‐adjusted productivity levels choose to export directly. Under certain parameter restrictions, the model shows that direct exporters tend to be larger and charge higher prices for their goods. In contrast to the literature, using Chinese customs data, we confirm that direct exporters do charge higher prices for their goods.     

NEW EXPORTER DYNAMICS

We document that new exporters initially export small amounts, grow gradually, and are most likely to exit the export market in their first few years. We find that the standard sunk‐cost model cannot replicate these new exporter dynamics: New exporters grow too large too quickly and live too long. In a modified sunk‐cost model that can account for these facts, the entry costs needed to match the data are three times smaller than in the sunk‐cost model. Dynamic models with richer plant‐level heterogeneity are needed.     

PRICE,PRODUCT QUALITY,AND EXPORTER DYNAMICS: EVIDENCE FROM CHINA

This article develops a model of heterogeneous firms that endogenously choose prices and product quality to build demand in export markets. New exporters optimally charge relatively low prices and produce low‐quality goods upon entry. Product quality, prices, and sales increase as demand grows. We structurally estimate model parameters using Chinese customs data. The estimated incentive to build future demand reduces average export prices by 0.7% and increases export sales by 4% upon entry. Endogenous demand accumulation causes estimated export prices, product quality, and sales to grow by 2.2%, 12%, and 79%, respectively, over the following five years.     

Quality screening and trade intermediaries: Evidence from China

We examine the quality‐screening role played by intermediaries in international trade, exploiting export data at the product level for Chinese exporters. We uncover substantial heterogeneity among intermediaries, and distinguish two types: generalized and specialized intermediaries. We find strong evidence of a quality‐verification role for specialized intermediaries: they are more prevalent in products with greater quality dispersion among local exporters, and export goods of higher quality than do generalized intermediaries. Our results suggest that specialized intermediaries have the capacity to reduce the incidence of quality problems.     

The Domestic Politics of Institutional Design: Producer Preferences over Trade Agreement Rules

What explains variation in the design of international institutions? Recent literature shows that providing members with opportunities to shirk their contractual obligations actually promotes agreement formation and durability. Yet, in spite of these benefits, institutions continue to exhibit wide variation in the “flexibility” of their rules. I show that, in the context of preferential trade agreements (PTAs), the benefits of permitting escape are enjoyed unevenly across the market. In particular, import‐competing industries gain from the protection that escape clauses provide while their export‐dependent counterparts bear the costs. This asymmetry creates domestic political competition over agreement design between the two traded sectors of the market. I explore this competition using new data on the design of 330 PTA agreements since 1960.     

Export price adjustments under financial constraints

Exploiting data on the product‐destination‐level transactions of a large panel of Italian firms, we provide evidence that financial constraints affect price variation across exporters. Constrained exporters charge higher prices than do unconstrained firms that export to the same product‐destination market. This pattern is the result of a two‐fold effect. Distressed firms pass on their higher production costs through prices. However, they also charge higher mark‐ups. We explain this evidence referring to models in which rival firms produce different brands of the same product for customers with significant switching costs and producers face capital market imperfections when they need external financing. Our empirical investigations corroborate this explanation: price gaps are higher when switching costs or other forms of demand rigidity are expected to be more relevant.     

Export revenue and quality: Firm‐level evidence from developing countries

I combine firm‐level export data from eight low‐income and middle‐income countries to test the relation between export price and export revenue. Across‐firm estimations show a strong positive association between export price and export revenue. Within‐firm estimations show that firms generate larger export revenue from their high‐price products. The positive correlation between export price and export revenue is strong for manufactures, weak for primary commodities, and nonexistent for extractables. Results are robust to using an alternative quality measure and controlling for exporters’ market power.     

Innovation,trade and multi‐product firms

This paper contributes to the literature on the relationship between innovation and exports by developing a model that emphasizes the role of product innovation in explaining heterogeneity in export behaviour both across and within firms. The dynamic model assumes that firms invest to maintain and increase the portfolio of products they sell: innovation is a stochastic process whereby the probability to capture new business opportunities is a function of the number of goods already sold. Crucially, the model assumes two independent mechanisms to drive the extensive and the intensive margins of a firm's export. The resulting lack of (built‐in) correlation between the two margins is well reflected in the data and represents the main contribution of our theoretical framework. The model is consistent with several other empirical regularities that characterize multi‐product firms, such as the heavy tail in the distribution of the number of products exported by each firm, the strict hierarchy in the sales of products across markets, the substantial degree of product churning and the highly skewed distributions of export sales.     

GROUPED VARIATION IN FACTOR SHARES: AN APPLICATION TO MISALLOCATION

A striking feature of microlevel plant data is the presence of significant variation in factor cost shares across plants within an industry. We develop a methodology based on cluster analysis to decompose cost shares into idiosyncratic and group-specific components. We apply our methodology to Chilean plant-level data and find that group-specific variation accounts for approximately one-third of the variation in cost shares. We study the implications of these groups in cost shares on the gains from eliminating misallocation. We place bounds on their importance and find that ignoring them can overstate the gains from eliminating misallocation by up to one-third .     

Entry and Exit in International Markets: Evidence from Chilean Data*

Several studies examine the patterns and determinants of entry and exit in manufacturing industries. Not much work exists on entry and exit in international markets. This paper uses Chilean data to analyze the industry‐level determinants of entry and exit in export markets. First, we show as stylized facts that entry and exit rates differ across industries, vary over time, and are positively correlated. Then, we study the main determinants of these patterns. Our econometric analysis shows that within‐industry heterogeneity, measured by differences in productivity or other firm characteristics, has a significant effect on plant turnover in international markets. Our findings reveal that trade costs, factor intensities, and fluctuations in the real exchange rate play a minor role explaining entry and exit. This last result is consistent with hysteresis in international markets.     

Can Production Subsidies Explain China's Export Performance? Evidence from Firm‐level Data*

This paper analyses the relationship between production subsidies and firms’ export performance using a very comprehensive and recent firm‐level database and controlling for the endogeneity of subsidies. It documents robust evidence that production subsidies stimulate export activity at the intensive margin, although this effect is conditional on firm characteristics. In particular, the positive relationship between subsidies and the intensive margin of exports is strongest among profit‐making firms, firms in capital‐intensive industries, and those located in non‐coastal regions. Compared to firm characteristics, the extent of heterogeneity across ownership structure (SOEs, collectives, and privately owned firms) proves to be relatively less important.     

Why firms set different export prices? Evidence from Spain

Using firm-level export data for the 2010–2014 period, we investigate the variation of export prices across and within Spanish manufacturing firms. We find that more productive firms set higher export prices. However, this result is not robust to controlling for other firm-level characteristics and alternative productivity measures. We show that firms set higher export prices in more distant markets and in destinations with high GDP per capita, and lower export prices in large and low-competition markets. These latter results suggest that firms adjust the quality of their products to destination characteristics.     

Legal Reform,Contract Enforcement and Firm Size in Mexico

The variation in legal system quality across states in Mexico is used to examine the relationship between judicial quality and firm size over the course of the 2000s, when systemic changes were taking place. Using economic census microdata and survey‐based measures of legal institutions, a robust effect of judicial quality is observed on the firm size distribution and efficiency, instrumenting for underlying historical determinants of institutions. Indicative evidence is found that the effect is strongest in more capital‐intensive industries. Market size and distance‐to‐market are also found to matter for firm size outcomes, consistent with the new trade literature.     

TECHNOLOGY SPECIALIZATION AND THE MAGNITUDE AND QUALITY OF EXPORTS

Abstract

This paper examines how technology specialization, measured by citation-weighed patents, affects trade flows. The paper analyzes the relationship between (i) technology specialization and export specialization across regions and (ii) the technology specialization of origin and destination and the quality of export flows. We find that the export specialization of regions corresponds to their technology specialization. Regions with higher technology specialization export products of higher quality, as indicated by higher prices. Moreover, export flows to destination countries with a high technology specialization consist of products of higher quality in the specific technology. The results are consistent with knowledge and technology being important for export performance and with regions with higher specialization in a technology being better equipped to produce high-quality products. They are also consistent with destinations of higher technology specialization, having a more pronounced demand for products of higher quality in the same technology.     

QUALITY CHOICE AND MARKET STRUCTURE: A DYNAMIC ANALYSIS OF NURSING HOME OLIGOPOLIES

This article develops a dynamic model of entry and exit to analyze quality choice and oligopoly market structure in the nursing home industry. I find significant heterogeneity in the competitive effects across market structures: Firms of similar quality levels compete more strongly than dissimilar firms. Sunken entry costs are extremely large, and quality adjustment behavior is governed by significant fixed adjustment costs. A proposal to eliminate low‐quality nursing homes is found to cause a large supply‐side shortage, and another proposal to lower entry costs has offered a perverse incentive to provide low quality of care.
