Oil Price Shocks, Income, and Democracy

We examine the effect of oil price fluctuations on democratic institutions over the 1960–2007 period. We also exploit the very persistent response of income to oil price fluctuations to study the effect of persistent (oil-price-driven) income shocks on democracy. Our results indicate that countries with greater net oil exports over GDP see improvements in democratic institutions following upturns in international oil prices. We estimate that a 1 percentage point increase in per capita GDP growth due to a positive oil price shock increases the Polity democracy score by around 0.2 percentage points on impact and by around 2 percentage points in the long run. The effect on the probability of a democratic transition is around 0.4 percentage points.

Voting Alone? The Political and Cultural Consequences of Commercial TV

We investigate the long-term impact of early exposure to Berlusconi’s commercial TV network, Mediaset, on voting behavior and civic engagement in Italy. To do so, we exploit differences in Mediaset signal reception across Italian municipalities due to the network’s staggered introduction over the national territory and to idiosyncratic geomorphological factors. We find that municipalities exposed to Mediaset prior to 1985 exhibit greater electoral support for Berlusconi’s party in 1994, when he first ran for office, relative to municipalities that were exposed only later on. This difference, estimated between 1 and 2 percentage points, is extremely robust and tends to persist in the following four elections. This effect can hardly be attributed to differential exposure to partisan news bias since, prior to 1985, content on Mediaset channels was dominated by light-entertainment programs and no news programs were broadcast until 1991, by which time the network was accessible to the entire population. Instead, we present evidence that early exposure to commercial TV was associated with a substantial decline in social capital consistent with the diffusion of a culture of individualism and civic disengagement that favored the political success of Berlusconi.

The Asian Crisis: What Did Local Stock Markets Expect?

In this paper we investigate whether cross-sectional information from local equity markets contained information on devaluation expectations during the Asian crisis. We concentrate on the information content of equity prices as these markets were in general the largest and most liquid at the time and, thus, presumably the best carriers of information. Using an event-study approach for the period leading up to each of the devaluations which occurred during the Asian crisis (namely those of Indonesia, Korea, Malaysia, the Philippines and Thailand), we compare returns in the equity prices of exporting and non-exporting firms. This is based on the assumption that the expectation of a devaluation should help the stock of exporting firms outperform those of non-exporting firms. Overall we do find some evidence supporting this hypothesis, although at different degrees depending on the country. Our second finding is that local equity market prices, as reflected in the different patterns seen for exporters and non-exporters, did to at least to some extent price in the possibility that the Thai devaluation would be followed by other countries in the region.
