Ubiquitin chains are formed as structurally distinct polymers via different linkages, and several chain types including K33-linkage remain uncharacterized. Here, we describe a role for K33-polyubiquitination in protein trafficking. We show that the Cullin 3 (Cul3) substrate adaptor KLHL20 is localized to the trans-Golgi network (TGN) and is important for post-Golgi trafficking by promoting the ...

This paper presents a strategic model of common value elections with endogenous information acquisition. It proves that majoritarian elections can fail to aggregate information when voters have heterogeneous skills. Informational inefficiencies can be partially corrected by improving the skills of the electors as the population increases, or by limiting participation to the most competent citiz...

We analyze the influence of IMF and World Bank programs on political regime transitions. We develop an extended version of Acemoglu and Robinson’s [American Economic Review 91, 2001] model of political transitions to show how the anticipation of new loans from international financial institutions can trigger political transitions which would not otherwise have taken place. We test this unexplor...

Using cross-country data from a sample of low, middle and high-income countries, the paper provides the first empirical test of the empirical relationships between national measures of social capital (civic and public), social divergence and social capacity upon various indicators of national environmental performance. The results indicate a possible link between public social capital (democrac...

In this paper, I examine the effects of money supply, aggregate spending, and aggregate supply shocks on real US stock prices in a structural vector autoregression framework. Overall, the empirical results indicate that each macro shock has important effects on real stock prices. The real stock price impulse responses to the various macro shocks conform to the standard present-value equity valu...

Prior studies have documented that stock returns are abnormally high during the years following share repurchases and abnormally low following seasoned equity offerings, relative to various benchmarks of expected returns. While we confirm this evidence in the event data as of 2002, we do not find robust long-run abnormal returns following either stock repurchases or issuances after 2002. Instit...

Long-term comovements of national stock markets in three EMS (European Monetary System) countries—France, Germany and Italy—are examined. The EMS stock markets are found to display long-term comovements governed by two common permanent components. To identify some interpretable sources of such long-term market comovements, the study explores whether they can be linked to similar comovements in ...

This paper analyzes the relations among firm-level stock option portfolio incentives, investment, and firm value based on a sample of Finnish firms during the time period 1987 – 2000. Utilizing exact and complete information regarding stock option portfolio characteristics, we find some evidence that firm investment is increasing in the incentives to increase stock price (delta) and risk (vega)...

This paper examines the relationship between stock returns and inflation. We focus on various econometric techniques to test this relationship, using monthly values of the Athens Stock Exchange Price index and the Greek Consumer Price index over the period 1988-2002. The results from a simple OLS model show evidence of a positive but not significant relationship, while when we consider a system...

Moving on from [Coleman, J.S., 1990. Foundations of Social Theory. Belknap Press of Harvard University Press, Cambridge, MA, London] and [Putnam, R.D., Leonardi, R., Nanetti, R.Y., 1993. Making Democracy Work Civic Traditions in Modern Italy. Princeton University Press, Princeton, NJ, Chichester], an ever-growing literature claims that repeating trustful interactions in the economy do sediment ...
