ECONOMIC FREEDOM AND INCOME INEQUALITY REVISITED: EVIDENCE FROM A PANEL ERROR CORRECTION MODEL

We investigate the causal relationship between income inequality and economic freedom using data from U.S. states over the period 1981 to 2004 within a panel error correction model framework. The results indicate bidirectional causality between income inequality and economic freedom in both the short and the long run. These results suggest that high income inequality may cause states to implement redistributive policies causing economic freedom to decline. As economic freedom declines, income inequality rises even more. In other words, it is quite possible for a state to get caught in a vicious circle of high income inequality and heavy redistribution.

Market Segmentation and Cross‐predictability of Returns

We present evidence supporting the hypothesis that due to investor specialization and market segmentation, value‐relevant information diffuses gradually in financial markets. Using the stock market as our setting, we find that (i) stocks that are in economically related supplier and customer industries cross‐predict each other's returns, (ii) the magnitude of return cross‐predictability declines with the number of informed investors in the market as proxied by the level of analyst coverage and institutional ownership, and (iii) changes in the stock holdings of institutional investors mirror the model trading behavior of informed investors.     

ETHNIC DIVERSITY AND TRUST

Using data from U.S. states, I investigate the relationship between ethnic diversity and trust. I find a negative relationship between ethnic polarization and trust and a U‐shaped relationship between ethnic fractionalization and trust. According to my estimations, (a) going from an ethnic polarization index (PI) of 0 to an ethnic PI of 1 decreases trust by almost 12% points; and (b) trust is minimized when the ethnic fractionalization index is equal to 0.34.

Corporate Diversification and the Cost of Capital

We examine whether organizational form matters for a firm's cost of capital. Contrary to the conventional view, we argue that coinsurance among a firm's business units can reduce systematic risk through the avoidance of countercyclical deadweight costs. We find that diversified firms have, on average, a lower cost of capital than comparable portfolios of stand‐alone firms. In addition, diversified firms with less correlated segment cash flows have a lower cost of capital, consistent with a coinsurance effect. Holding cash flows constant, our estimates imply an average value gain of approximately 5% when moving from the highest to the lowest cash flow correlation quintile.     

CORRUPTION AND INCOME INEQUALITY IN THE UNITED STATES

In this study we analyze the effects of corruption on income inequality. Our analysis advances the existing literature in three ways. First, instead of using one of the corruption indices assembled by various investment risk services, we use an objective measure of corruption: the number of public officials convicted in a state for crimes related to corruption. Second, we minimize the problems which are likely to arise because of data incomparability by examining the differences in income inequality across the United States. Finally, we exploit both time series and cross‐sectional variation in the data. We find robust evidence that an increase in corruption increases income inequality. (JEL D31, D73, I32)
