Employing a wide range of individual-level surveys, we study the extent of cultural and institutional heterogeneity within the EU and how this changed between 1980 and 2008. We present several novel empirical regularities that paint a complex picture. While Europe has experienced both systematic economic convergence and an increased coordination across national and subnational business cycles since 1980, this was not accompanied by cultural nor institutional convergence. Such persistent heterogeneity does not necessarily spell doom for further political integration, however. Compared to observed heterogeneity within member states themselves, or in well functioning federations such as the US, cultural diversity across EU members is a similar order of magnitude. The main stumbling block on the road to further political integration may not be heterogeneity in fundamental cultural traits, but other cleavages, such as national identities.

Do banks with low capital extend excessive credit to weak firms, and does this matter for aggregate efficiency? Using a unique data set that covers almost all bank-firm relationships in Italy in the period 2008-2013, we find that, during the Eurozone financial crisis: (i) Under-capitalized banks cut credit to healthy firms (but not to zombie firms) and are more likely to prolong a credit relationship with a zombie firm, compared to stronger banks. (ii) In areas-sectors with more lowcapital banks, zombie firms are more likely to survive and non-zombies are more likely to go bankrupt; (iii) Nevertheless, bank under-capitalization does not hurt the growth rate of healthy firms, while it allows zombie firms to grow faster. This goes against previous in

uential findings that, we argue, face serious identification problems. Thus, while banks with low capital can be an important source of aggregate inefficiency in the long run, their contribution to the severity of the great recession via capital misallocation was modest.

This paper develops a theoretical model of voters' and politicians' behavior based on the notion that voters focus disproportionately on, and hence overweight, certain attributes of policies. We assume that policies have two attributes and that voters focus more on the attribute in which their options differ more. First, we consider exogenous policies and show that voters' focusing polarizes the electorate. Second, we consider the endogenous supply of policies by office-motivated politicians who take voters' distorted focus into account. We show that focusing leads to inefficient policies, which cater excessively to a subset of voters: social groups that are larger, have more distorted focus, are more moderate, and are more sensitive to changes in a single attribute are more influential. Finally, we show that augmenting the classical models of voting and electoral competition with focusing can contribute to explain puzzling stylized facts as the inverse correlation between income inequality and redistribution or the backlash effect of extreme policies.

The economic impact of exported institutions depends on the underlying cultural environment of the receiving country. We present evidence that cultural proximity between the exporting and the receiving country positively affects the adoption of new institutions and the resulting long-term economic outcomes. We obtain this result by combining new information on pre-Napoleonic kingdoms with county-level census data from nineteenthcentury Prussia. This environment allows us to exploit a quasi-natural experiment generated by radical Napoleonic institutional reforms and deeply rooted cultural heterogeneity across Prussian counties. We show that counties that are culturally more similar to France, in terms of either religious affiliation or historical exposure to French culture, display better long-term economic performance. We analyze a range of alternative explanations and suggest that our findings are most easily explained by cultural proximity facilitating the adoption of new institutions.

This paper documents time-variation in the relation between oil price and U.S. equity returns based on both reduced-form and structural analyses. Our reduced-form analysis suggests that a positive correlation between equity returns and oil price has emerged starting from the financial crisis. Based on our structural analysis, we find that oil-specific demand shocks have had positive effects on the U.S. stock market since 2008 as opposed to oil supply shocks, which have no large effects on stock re turns. We also show that the time variation in the parameters of the structural VAR is very well explained by the level of the U.S. short-term interest rate and shifts in consumer confidence.

We model theoretically and quantify empirically the impact of informational frictions on managerial decisions in the context of mergers and acquisitions. In particular, we focus on how bid premiums and methods of payment are affected by the bidder and target firms' degrees of opacity. To this end, we model the negotiation between bidder and target as a signaling game with two-sided private information. We then empirically test the model's predictions concerning the effects of target and bidder opacity on the simultaneous determination of the method of payment and the bid premium, by conditioning cross-sectionally on the basis of firms' stock trading properties, which we interpret as representative of individual firm opacity. Consistently with the predictions of our model, we find, by studying a sample of bids by and for U.S. publicly listed firms over the period 1985-2014, that both the likelihood of a stock bid and the bid premium increase with the opacity of the target, while the opacity of the bidder is related to lower bid premiums.

We model an order book with liquidity rebates (make fees) and trading fees (take fees) that faces intermarket competition, and use the models insights to explain changes in market quality and market shares following changes in make-take fees. As predicted by our model, we document that fee changes by one venue affect market quality and market shares for all venues that compete for order flow. Furthermore, we document cross-sectional differences in changes in market quality and market shares following a simultaneous decrease in both make and take fees consistent with traders in large (small) capitalization stocks being more sensitive to the change in make (take) fees.

Today, income inequality in Sub-Saharan Africa is exceptionally high. In this paper, we study whether present-day inequality can be traced back to the colonial period by reconstructing income distributions in a sample of representative colonies. To do so, we use data from colonial records to build new social tables for French colonies in West and Central Africa and we combine them with available information on British colonies in East and Southern Africa. We find that inequality in Africa is not a recent phenomenon. Income inequality was extremely high during the colonial period, in particular because of the huge income differential between Africans and European settlers. Nevertheless, it tended to reduce over time and the post-colonial period is characterized by much lower inequality. Interestingly, the decline of inequality is not necessarily a consequence of independence: the trends toward reduction started under colonial rule.

We characterize consistent random choice rules in terms of the optimality of the support. We then proceed to study stochastic choice in a consumer theory setting. We prove a law of demand for stochastic choice. We then move to a temporal setting where we characterize the softmax decision criterion.

The purpose of this note is to discuss the relation between model uncertainty in risk analysis and decision theory.
