Guest workers: adequate incentives for voluntary return

A guest-worker program can be a very flexible and convenient way of meeting labor shortages in a host country, assuming that the migrants obeythe rules. This paper investigates the conditions under which guest workers have sufficient incentives for voluntary return to their country of origin when their work permits expire. The analysis is conducted in the context of a lenient…

Debt levels, debt composition, and sovereign spreads in emerging and advanced economies

This paper studies the relationship between sovereign spreads and the interaction between debt composition and debt levels in advanced and emerging market countries. It finds that in emerging market countries there is a significant correlation between spreads and debt levels. This correlation, however, is not statistically significant in countries where most public debt is…

An evaluation of the impact of the natural forest protection programme on rural household livelihoods

In this paper, we estimate the impact on local household livelihoods of the Natural Forest Protection Programme (NFPP), the largest logging ban programme in the world that aims to protect watershed and conserve natural forests. In doing so we use a series of policy evaluation micro-econometric techniques to assess the impacts of the NFPP on two interrelated facets of household…

Currency crises in reverse: do large real exchange rate appreciations matter for growth?

While currency crises have been extensively studied, the opposite phenomenon, large appreciations, has been far less researched. We fill this gap by providing an empirical exploration of historical episodes of large real exchange rate appreciations, using a sample of 28 advanced and 25 emerging market economies, with annual data going back to 1970. We focus on the impact of large…

Understanding Rating Addiction: US Courts and the Origins of Rating Agencies’ Regulatory License (1900-1940)

This paper discusses the “regulatory license” view that reliance by regulators on the output of rating agencies in the 1930s “caused” the agencies to become a central part of the fabric of the US financial system. Exploring pre-1930 court records, we find evidence of a growing reliance on the agencies that pre-dates the regulatory moves of the 1930s. We argue that courts began using…

Pessimism, optimism and credit rationing

In their celebrated contribution on credit rationing, Stiglitz and Weiss (1981) showed that the expected return to the borrower on a loan is increasing in the risk of the project it funds. In this paper, I show that their results do not necessarily carry over to the case where the agents’ preferences can be described by rank-dependent expected utility (RDEU). In particular, a…

Public debt and economic growth in advanced economies: a survey

This paper surveys the recent literature on the links between public debt and economic growth in advanced economies. We find that theoretical models yield ambiguous results. Whether high levels of public debt have a negative effect on long-run growth is thus an empirical question. While many papers have found a negative correlation between debt and growth, our reading of the…

Documenting legal dissonance: regulation of (and by) payback killing in Papua New Guinea

We provide a simple model for considering the interaction between multiple legal regimes existing simultaneously within a single jurisdiction. We demonstrate that, even when the fundamental relationship between outputs of such regimes is to behave as substitutes for one another, the existence of negative externalities between the enforcement technologies can result in the withdrawal…

The making of a (vice-)president: party politics, ethnicity, village loyalty and community-driven development

African politics are often said to be dominated by ethnic divides, with the ensuing policies implemented by leaders being based almost exclusively on their ethnic power base. In this paper, we demonstrate that the village of origin of democratically-elected leaders matters for the attribution of development projects in the context of one of the largest Community-Driven Development (…

Corruption and the curse: the dictator's choice

We develop a dynamic discrete choice model of a self-interested and unchecked ruler making decisions regarding the exploitation of a resource-rich country. This dictator makes the recursive choice between either investing domestically to live off the productivity of the country while facing the risk of being ousted, or looting the country’s riches by liquefying the resources and…

A bargaining theory of trade invoicing and pricing

We develop a theoretical model of international trade pricing in which individual exporters and importers bargain over the transaction price and exposure to exchange rate fluctuations. We find that the choice of price and invoicing currency respects the full market structure, including the extent of fragmentation and the degree of heterogeneity across importers and across exporters…

Trade effects of export taxes

Export taxes usage has recently risen. They are widely presumed to affect trade, but the lack of data has prevented a systematic evaluation of their trade effects. Based on a new dataset of tax rates at the product level, this paper estimates the distortionary trade effects of export taxes. The results, which are based on theory-consistent estimation of a structural gravity model,…

Panel export taxes (PET) dataset : new data on export tax rates

This paper describes a newly collected dataset on export tax rates, which provides comprehensive coverage for 20 countries, 2 time periods and all products at HS6 level. Export tax rates are based on national government documentation, including preferential provisions for partner countries.

Does community driven development work? : evidence from Senegal

Community Driven Development (CDD) programs are an extremely important component of the World Bank’s portfolio in the developing world, representing close to $7 billion in 2003, yet solid empirical evidence on their impact is relatively scarce, especially for Subsaharan Africa. In this paper, we consider the impact on access to basic services, household expenditures and child…

Essential heterogeneity in the impact of community driven development

We consider essential heterogeneity in the impact of a large-scale Community-Driven Development (CDD) program in Senegal. Essential heterogeneity arises when unobservables determine the idiosyncratic gains from participation in a program, thereby generating correlation between treatment effects and selection. Standard instrumental variables estimates are shown to provide an extremely…
