Taking Stock of the Evidence on Microfinancial Interventions

We review the empirical evidence on microfinance and asset grants to the ultra poor or microentrepreneurs and use quantitative economic theory to account for this evidence. Properly executed, these interventions can help segments of the population increase their income and consumption, but neither literature gives much reason to believe that such interventions can lead to wide-scale, transformative impacts akin to escaping aggregate poverty traps.

The great trade collapse of 2008-2009: an inventory adjustment?

This paper examines the role of inventories in the decline of production, trade, and expenditures in the US in the economic crisis of late 2008 and 2009. Empirically, the authors show that international trade declined more drastically than trade-weighted production or absorption and there was a sizeable inventory adjustment. This is most clearly evident for autos, the industry with the largest drop in trade. However, relative to the magnitude of the US downturn, these movements in trade are quite typical. The authors develop a two-country general equilibrium model with endogenous inventory ...

Microeconomic uncertainty, international trade, and aggregate fluctuations

The extent and direction of causation between micro volatility and business cycles are debated. We examine, empirically and theoretically, the source and effects of fluctuations in the dispersion of producer-level sales and production over the business cycle. On the theoretical side, we study the expect of exogenous first- and second-moment shocks to producer-level productivity in a two-country DSGE model with heterogeneous producers and an endogenous dynamic export participation decision. First-moment shocks cause endogenous fluctuations in producer-level dispersion by reallocating ...

Working Paper
Inventories, lumpy trade, and large devaluations

Fixed transaction costs and delivery lags are important costs of international trade. These costs lead firms to import infrequently and hold substantially larger inventories of imported goods than domestic goods. Using multiple sources of data, we document these facts. We then show that a parsimoniously parameterized model economy with importers facing an (S, s)-type inventory management problem successfully accounts for these features of the data. Moreover, the model can account for import and import price dynamics in the aftermath of large devaluations. In particular, desired inventory ...

Scale and the origins of structural change

Structural change involves a broad set of trends: (i) sectoral reallocations, (ii) rich movements of productive activities between home and market, and (iii) an increase in the scale of productive units. After extending these facts, we develop a model to explain them within a unified framework. The crucial distinction between manufacturing, services, and home production is the scale of the productive unit. Scale technologies give rise to industrialization and the marketization of previously home produced activities. The rise of mass consumption leads to an expansion of manufacturing, but a ...

Why are goods so cheap in some countries?

Looking around the world, we observe substantial differences across countries in prices for most goods. These price differences also tend to be positively correlated with income differences, so that citizens of high-income countries tend to pay more for the same goods than citizens in low-income countries. In ?Why Are Goods So Cheap in Some Countries?,? George Alessandria and Joseph Kaboski summarize some of the evidence related to the big price differences across countries for a broad set of goods. They then discuss the relationship between prices and income levels and some possible ...

Working Paper
Trade wedges, inventories, and international business cycles

The large, persistent fluctuations in international trade that cannot be explained in standard models by changes in expenditures and relative prices are often attributed to trade wedges. We show that these trade wedges can reflect the decisions of importers to change their inventory holdings. We find that a two-country model of international business cycles with an inventory management decision can generate trade flows and wedges consistent with the data. Moreover, matching trade flows alters the international transmission of business cycles. Specifically, real net exports become ...

Working Paper
U.S. trade and inventory dynamics

The authors examine the source of the large fall and rebound in U.S. trade in the recent recession. While trade fell and rebounded more than expenditures or production of traded goods, they find that relative to the magnitude of the downturn, these trade fluctuations were in line with those in previous business cycle fluctuations. The authors argue that the high volatility of trade is attributed to more severe inventory management considerations of firms involved in international trade. They present empirical evidence for autos as well as at the aggregate level that the adjustment of ...

Violating purchasing power parity.

This paper demonstrates that deviations from the law of one price are an important source of violations of absolute PPP across countries. Using highly disaggregated U.S. export data, we document evidence of systematic international price discrimination based on the local wage of consumers in the destination market. We show that most violations from absolute PPP can also be explained by international differences in wages. We find very little additional explanation is due to differences in income per capita. Developing and calibrating a model of pricing-to-market based on search frictions and ...
