Testing the Unstable Middle and Two Corners Hypotheses About Exchange Rate Regimes

The recent rash of international currency crises has generated considerable interest in the role that exchange rate regimes have played in contributing to these crises. Many economists have argued that efforts to operate adjustably pegged exchange rate regimes have been a major contributor to “the unstable middle” hypothesis and some have argued that this unstable middle is so broad that only the two corners of hard fixes or floating rates will be stable in a world of high capital mobility—the two corners or bipolar hypothesis. Two recent empirical studies by researchers at the International Monetary Fund reach opposing conclusions on these issues. We examine the issue further and show that conclusions can be quite sensitive to how exchange rate regimes are grouped into categories and the measures of currency crises that are used. In general we find that the dead center of the adjustable peg is by far the most crisis prone broad type of exchange rate regimes, but that countries need not go all the way to freely floating rates or hard fixes to substantially reduce the risks of currency crises.

Social Capital and the Shadow Economy

Viewed in a wider context of paid and unpaid informal economic activities, the shadow economy highlights the little recognized ambivalence of social capital as both potentially positive and negative in outcomes for different groups in the economy. Using a concept of social capital as access to durable networks of actual and virtual resources, as claimed by Pierre Bourdieu, I examine the shadow economy as a source of both resilience and repression, intimately connected to the formal economy and tied to a neo-liberal agenda. I draw from review activities I have previously conducted on the informal economy in disadvantaged neighborhoods and from research on social capital in the economy in a European context.

Heterogeneity effects from market interventions

The aim of this paper is to test whether the European Commission activities generate a heterogeneity effect on the merging parties. A sample of 74 firms involved in 45 contested merger and acquisition operations during the years 1990 to 1999 is used. The methodology is based on the GARCH framework. The main result is that, globally, the DGC interventions seem not to reduce significantly the heterogeneity among investors, except for the operations where it takes strong decisions like prohibition. In these last cases, the signal coming from the DGC encompasses valuable information and is well understood by market participants.     

Labor Markets and Monetary Policy

Headline employment numbers have been consistent with previous recoveries from recession. Behind the headlines, however, there are troubling data that suggest that the recovery of labor markets is weaker than what would be suggested by prior experience. In particular, labor force participation is weaker than expected, and the duration of unemployment has been longer. This paper describes the dimensions of the problems, their implications, and issues concerning whether the U.S. Federal Reserve could have done more to forestall them—particularly with respect to its Large Scale Asset Purchases program.     

Exploring the Existence of Local and Global Knowledge Spillovers:Evidence from Plant‐Level Data*

We investigate the existence of local (within‐country) and global (between‐country) knowledge spillovers within a single analytical framework. Our study is based on a detailed database of domestically owned and foreign‐affiliated manufacturing plants located in Ireland. The results of our econometric analysis show that domestically owned plants benefit from the research and development (R&D) activities of other domestically owned plants, as well as from R&D activities conducted in the country of origin of foreign‐owned plants through their presence in Ireland. A fundamental difference between such locally generated and locally transmitted global spillovers appears to be that the latter are much less constrained by distance decay effects.     

Prevailing Protectionism Challenge to International Mining

An overall adjustment of global industries is going on and the global resource allocation layout is changing.Developed countries attempt to maintain the existing resource allocation layout while emerging countries such as China and India are getting involved in global resource allocation and are playing an increasingly active role.The reporter from China's Foreign Trade magazine had an interview with relevant offcials,experts and professionals in mining investment on such issues as the current characteristics of international mining market,the situation of international mining market in the year 2012 and the foreign investment direction of Chinese mining,and analyzed the above issues.     

Trust and corruption revisited: how and why trust and corruption shape each other

Graeff and Svendsen argue that low trust leads to corruption but corruption does not lower trust. I challenge this argument as well as their critique of Uslaner. I present evidence to show that there is a reciprocal relationship between trust and corruption.     

Heckscher–Ohlin theory when countries have different technologies

Rethinking the foundations of Heckscher–Ohlin theory when countries have different technologies, this paper shows how to make the proper adjustments for international productivity differences. The central tool is a factor conversion matrix that computes the local factor content of foreign Rybczynski effects. Factor-specific productivities are a special case of these more general linear relationships.
