MODEL PRIORS REVISITED: INTERACTION TERMS IN BMA GROWTH APPLICATIONS

This paper provides a sensitivity analysis on the prior choice for interaction terms for the results of Masanjala and Papageorgiou (Rough and lonely road to prosperity. Journal of Applied Econometrics 2008; 23 : 671–682), which has been criticized for its implementation of interaction terms by Crespo Cuaresma (How different is Africa? Journal of Applied Econometrics 2011; 26 : 1041–1047). We find that the discussed priors have similar predictive power and we also evaluate alternative prior solutions that account for the special nature of interaction terms.

Constitutional protection of economic rights: The Swiss and U.S. experience in comparison

This paper analyzes the contribution of the Swiss and the U.S. Constitution to protect economic liberties, and compares the different strategies that both constitutions rely on to achieve this goal. Pertinent provisions in the Swiss Constitution are rather precise but relatively easy to change, whereas the U.S. Constitution is characterized by vaguely formulated constraints that are difficult to amend formally and that are interpreted by the Supreme Court. Nevertheless, the substantial constitutional changes that did occur in both countries seem to have followed strikingly similar patterns: Initially, regional integration through reciprocal market opening within both countries facilitated the constitutional protection of economic liberties. Subsequently, the constitutional protection of economic liberties eroded in both countries, especially against federal legislation, due to changes in the interpretation of the constitution through the courts, or by formal amendment. Lastly, both constitutions were not immune against sudden demands by special interest groups that were being raised during times of crisis or war.

Public capital stock and state productivity growth: Further evidence from an error components model

The contribution of different types of public infrastructure on private production is investigated using time-series of cross-section data for the 48 contiguous states over the period 1970–1986. A Cobb-Douglas production function is estimated with unobserved state-specific effects. Measurement errors in public capital stock and its components are detected and rectified.We would like to thank Baldev Raj and an anonymous referee for helpful comments. Also, Timothy J. Gronberg and Kay McAllister who thoroughly read the earlier draft and offered many constructive suggestions. We are, however, solely responsible for any remaining errors. The data set used in this research was generously provided by Alicia H. Munnell and Leah Cook of the Federal Reserve Bank of Boston.

Foreign Share, Insurance Density, and Penetration: An Analysis of the International Life Insurance Market

Recent trends toward liberalization and deregulation have sparked significant interest in the topic of international insurers' participation in foreign markets. This research develops a profile of foreign national market characteristics that attract international life insurer participation and additionally, empirically assesses the value that international participation has to the host market. Characteristics that are found to be statistically significant with respect to international participation include high levels of trade liberalization and/or low insurer market share concentration, high levels of national wealth, and high levels of government expenditure on social security retirement benefits. With respect to the benefits such participation provides, we see that the presence of international life insurers share positive relationships with both life insurance consumption and the magnitude of the role life insurance plays within the broader national economy of those host markets.     

The Market Structure–Performance Relationship in the International Insurance Sector

This article tests the applicability of the structure–conduct–performance (SCP) hypothesis in the international nonlife insurance marketplace. We employ a panel data regression methodology that includes 23 nations (developed and developing countries) over the time period of 1996 to 2003. The results reveal that the interaction of market liberalization and market concentration shares a complex relationship with market profitability. Our results show that the expectations associated with the SCP hypothesis are supported when the levels of liberalization are low. However, for markets that are highly liberalized the presence of foreign insurers significantly alters the dynamics of nonlife insurance markets.     

An Investigation Into the Diversification–Performance Relationship in the U.S. Property–Liability Insurance Industry

This article investigates the relationship between product diversification and firm performance in the U.S. property–liability insurance industry using data over the 1994 through 2002 time period. Using various measures of product diversification and firm performance, we find that the extent of product diversification shares a complex and nonlinear relationship with firm performance. Our findings suggest that performance benefits associated with product diversification are contingent upon an insurer's degree of geographic diversification. Robustness tests using subsamples and market returns for public firms show consistent results.     

What Does the Corporate Bond Market Know?

Do related markets reflect new information simultaneously? For high‐yield bonds, a large abnormal price decline in a corporation's most liquid bond over a month is followed by an average abnormal stock price decline of ?1.42%. This effect is larger for stocks that have increased in value and for volatile stocks. It is also larger for bonds with high coupons and shorter maturities. These results support the view that high‐yield corporate bonds have an informational edge when news is negative and stock returns are noisy, and add to the growing literature on the substantial lags in price discovery between related markets.
