Entry costs, industry structure, and cross-country income and TFP differences

Entry costs vary dramatically across countries. To assess their impact on cross-country differences in output and TFP, we construct a model with endogenous entry and operation decisions by firms. We calibrate the model to match the U.S. distribution of employment and firms by size. Higher entry costs lead to greater misallocation of productive factors and lower TFP and output. In the model, countries in the lowest decile of the entry costs distribution have 1.32 to 1.45 times higher TFP and 1.52 to 1.75 times higher output per worker than countries in the highest decile. As in the data, higher entry costs are associated with lower entry rates and business density.

What Is Common Among Return Anomalies? Evidence from Insider Trading

For a broad set of anomalies, we establish a common pattern of underreaction to information contained in preceding insider trading activity. Our main analysis focuses on the anomalies' short legs, which generate persistent negative abnormal returns. For stocks in the short legs, future returns are systematically related to the information signal contained in preceding insider trading activity, indicating underreaction. For insider trading information, we consider the possibility of net buying, net selling, and no trading (or silence). The underreaction effect is economically significant, with the most negative signal accounting for an average of 71% of short-leg returns. This underreaction effect survives numerous robustness checks and remains important after accounting for investor sentiment, information environment, and limits to arbitrage.     

Beliefs regarding fundamental value and optimal investing

Standard optimal portfolio selection models take no account of the special information that active investors believe they possess. For example, active investors who believe they can place bounds on the price of a security will want to use that information when assessing risk and expected return in order to construct an optimal portfolio. In this paper, we use two continuous-time models to analyze how placing boundaries on the price of a stock affects assessed risk, expected returns, and the optimal holdings of an active investor, and how those vary as a function of the relation between the stock price and the boundaries. In particular, the optimal strategy takes significant long/short positions as the price nears its lower/upper boundary.     

Cross-country income convergence revisited

We reassess convergence of income across countries and its determinants. The ergodic distribution of output per worker features multiple modes. In contrast to previous findings, productivity in the long run is unimodal. The long-run distribution of human capital is multimodal.     

The Reaction of Real Estate–Related Industries to the Monetary Policy Actions

We study the impact of changes in U.S. monetary policy on the equity returns of real estate–related industries. We find that, over the 1989–2005 sample period covered in our study, a hypothetical unexpected rate cut of 25 basis points (bps) is associated with an increase of about 170 bps in the value‐weighted returns of real estate–related industries. We find that monetary policy impacts the stock prices in real estate–related industries through its impact on the future expected stock returns and not on real interest rates or expected future dividends. There is also some evidence of asymmetry in the responses of the industry returns to the monetary policy actions. A strong stock price response to reversals in the direction of the Federal Reserve's monetary policy is reported.     

Non-performing loans, prospective bailouts, and Japan's slowdown

The delay in the government bailout of the financial sector played a key role in Japan's slowdown during the 1990s and early 2000s. This argument is articulated in a general equilibrium model in which the government provides deposit insurance to the financial sector. The existence of non-performing loans, combined with a delay in the bailout, leads to a persistent decline in economic activity. Consistent with Japan's experience, the decline in output is caused not only by a fall in investment, but also by a decline in labor and total factor productivity.     

Institutions and growth in limited access societies

We build a dynamic political economy model with a two-class society, workers and the elite, in which the elite formation, the innovation rate and fiscal policy are endogenous. The model generates a mapping between institutions and patterns of growth consistent with empirical evidence. Ex ante, when facing constraints in choosing institutions, the elite may delegate policy control to some of its members, even though such delegation exacerbates the conflict within the elite and causes policy failures. Committing to such institutional arrangements prevents more harmful outcomes, such as rapid entry and subsequent deterioration of the elite?s economic and political power.     

The effects of exchange rate volatility on exports: evidence from Armenia

The article examines how the volatility of exchange rate affected Armenia’s export to its main trading partner, Russia, in the period from January 2007 to February 2016. Along with real foreign income and competitiveness, the exchange rate volatility is considered as a determinant of real export. The estimation results indicate that the exchange rate volatility has negative significant effects on real export both in the long run and in the short run.     

Entry costs and cross-country differences in productivity and output

This paper contributes to the literature on cross-country income differences by studying the effect of entry barriers on productivity and output. Using instrumental variable regressions I show that higher entry costs significantly reduce output per worker and that they do so by lowering total factor productivity. In particular, an increase in entry costs by 80% of income per capita, which is one half of their standard deviation in my sample, is estimated to decrease total factor productivity and output per worker by 22% and 29%, respectively.
