What Is the Equity-Efficiency Tradeoff when Maintaining Wells in Rural Haiti?
This paper quantitatively compares water infrastructure interventions that prioritize equity with those that prioritize efficiency. The community-based model developed by Haiti Outreach (HO) trains communities to operate and maintain wells, and has clear effi ciency gains over the status quo aid model in Haiti that gives communities wells: HO?s wells were 8.7 percentage points more likely to be functioning after one year than similarly-constructed wells managed under the status quo model. Because HO?s model includes user fees, which raise concerns about equity, I quantify the ...

Financial Development and International Trade
This paper studies the industry-level and aggregate implications of financial development on international trade. I set up a multi-industry general equilibrium model of international trade with input-output linkages and heterogeneous firms subject to financial frictions. Industries differ in capital-intensity, which leads to differences in external finance dependence. The model is parameterized to match key features of firm-level data. Financial development leads to substantial reallocation of international trade shares from labor- to capital-intensive industries, with minor effects at the ...

The Aggregate Implications of Size-Dependent Distortions
This article examines the aggregate implications of size-dependent distortions. These regulations misallocate labor across firms and hence reduce aggregate productivity. The author then considers a case study of labor laws in France, where firms with 50 employees or more face substantially more regulation than firms with fewer than 50. The size distribution of firms is visibly distorted by these regulations: There are many firms with exactly 49 employees. A quantitative model is developed with a payroll tax of 0.15 percent that applies only to firms with more than 50 employees. Removing the ...

The Making of an Economic Superpower―Unlocking China’s Secret of Rapid Industrialization
The rise of China is no doubt the most important event in world economic history since the Industrial Revolution. The institutional theory of development based on a dichotomy of extractive vs. inclusive political institutions cannot explain China?s rise. This article argues that only a radical reinterpretation of the history of the Industrial Revolution and the rise of the West (as incorrectly portrayed by the institutional theory) can fully explain China?s growth miracle and why the determined rise of China is unstoppable. Conversely, China?s spectacular and rapid transformation from an ...

Lights, camera,...income! Estimating poverty using national accounts, survey means, and lights
In this paper, we try to understand whether measures of GDP per capita taken from national accounts or measures of mean income or consumption derived from household surveys better proxy for true income per capita. We propose a data-driven method to assess the relative quality of GDP per capita versus survey means by comparing the evolution of each series to the evolution of satellite-recorded nighttime lights. Our main assumption, which is robust to a variety of specification checks, is that the measurement error in nighttime lights is unrelated to the measurement errors in either national ...

Can Self-Help Groups Really Be 'Self-Help'?
We provide an experimental and theoretical evaluation of a cost-reducing innovation in the delivery of "self-help group" microfinance services, in which privatized agents earn payments through membership fees for providing services. Under the status quo, agents are paid by an outside donor and offer members free services. In our multi-country randomized control trial we evaluate the change in this incentive scheme on agent behavior and performance, and on overall village-level outcomes. We find that privatized agents start groups, attract members, mobilize savings, and intermediate loans at ...

The home market, trade, and industrial structure
Does national market size matter for industrial structure? This has been suggested by theoretical work on "home market" effects, as in Krugman (1980, 1995). In this paper, I show that what previously was regarded as an assumption of convenience ? transport costs only for the differentiated goods ? matters a great deal. In a focal case in which differentiated and homogeneous goods have identical transport costs, the home market effect disappears. The paper discusses available evidence on the relative trade costs for differentiated and homogeneous goods. No compelling argument is found that ...

Explaining Educational Attainment across Countries and over Time
Consider the following facts. In 1950, the richest countries attained an average of 8 years of schooling whereas the poorest countries 1.3 years, a large 6-fold difference. By 2005, the difference in schooling declined to 2-fold because schooling increased faster in poor than in rich countries. What explains educational attainment differences across countries and their evolution over time? We consider an otherwise standard model of schooling featuring non- homothetic preferences and a labor supply margin to assess the quantitative contribution of productivity and life expectancy in explaining ...
