The world price of home bias

Theoretical arguments suggest that as the degree of a country's home bias increases, the global risk sharing between domestic and foreign investors will reduce and thereby increase the country's cost of capital. Consistent with this prediction, we find international differences in the cost of capital to be strongly and positively related to varying degrees of home bias for 38 markets. This finding is robust to different cost of capital proxies, different control variables, alternative home-bias measures, international tradability of stocks, and alternative specifications. Therefore, the overall evidence implies that countries may enjoy a significantly lower cost of capital by reducing the extent of their home bias and hence, increasing global risk sharing.     

A network perspective of the stock market

Complex networks are constructed to study correlations between the closing prices for all US stocks that were traded over two periods of time (from July 2005 to August 2007; and from June 2007 to May 2009). The nodes are the stocks, and the connections are determined by cross correlations of the variations of the stock prices, price returns and trading volumes within a chosen period of time. Specifically, a winner-take-all approach is used to determine if two nodes are connected by an edge. So far, no previous work has attempted to construct a full network of US stock prices that gives full information about their interdependence. We report that all networks based on connecting stocks of highly correlated stock prices, price returns and trading volumes, display a scalefree degree distribution. The results from this work clearly suggest that the variation of stock prices are strongly influenced by a relatively small number of stocks. We propose a new approach for selecting stocks for inclusion in a stock index and compare it with existing indexes. From the composition of the highly connected stocks, it can be concluded that the market is heavily dominated by stocks in the financial sector.     

Regulatory Capital Charges for Too‐Connected‐to‐Fail Institutions: A Practical Proposal

The recent financial crisis has highlighted once more that interconnectedness in the financial system is a major source of systemic risk. I suggest a practical way to levy regulatory capital charges based on the degree of interconnectedness among financial institutions. Namely, the charges are based on the institution's incremental contribution to systemic risk based on a risk budgeting approach. The imposition of such capital charges could go a long way towards internalizing the negative externalities associated with too‐connected‐to‐fail institutions and providing managerial incentives to strengthen an institution's solvency position, and avoid too much homogeneity and excessive reliance on the same counterparties in the financial industry.     

A global database of domestic and international tourist numbers at national and subnational level

We present a new, global database on tourist destinations. The database differs from other databases in that it includes both domestic and international tourists; and it contains, for the most important destinations, data at national level as well as at lower administrative levels. Missing observations are interpolated using statistical models. The data are freely accessible on the internet. Copyright © 2007 John Wiley & Sons, Ltd.     

A theorem on the identifiability of the von Neumann-Morgenstern utility function from asset demands

If the demand for risky assets is determined by the maximization of an analytical von Neumann-Morgenstern utility function, and if these demands are known as a function of the assets' prices, then this utility function can be constructed without ambiguity.     

Extending symbolic brands using their personality: Examining antecedents and implications towards brand image fit and brand dilution

This research provides a framework to achieve two objectives. First, it helps us to understand the implications of congruency of information, motivation, and perceived prestige orientation as antecedents to brand personality fit. Second, it examines the mediating role of brand image fit between brand personality fit and dilution of brand affect. The above is explained by using elaboration theory, conceptual coherence theory, and goal‐derived categorization theory. The results of the implication of elaboration theory on brand personality fit were mixed. While congruency of personality dimensions between parent and extension brands has bearings towards brand personality fit, the motivation of processing information did not. In contrast to brand image fit, this study showed that the prestige orientation of a brand did not influence brand personality fit. The subsequent mediation analysis demonstrated that brand personality fit is positively related to brand image fit, but neither of these two variables has any influence on dilution of brand affect. © 2007 Wiley Periodicals, Inc.     

Financial and nonfinancial performance measures: How do they affect job satisfaction?

Recent interest on the use of nonfinancial measures (e.g. in the Balanced Scorecard) generally assumes that such measures are essential to overcome the inadequacies of financial measures. However, it remains unclear (1) if the behavioural effects of these nonfinancial measures are different from those of financial measures; and (2) whether these effects are influenced by the relative importance of nonfinancial measures vis-à-vis financial measures. This study hypothesises that the use of performance measures for performance evaluation will significantly affect managers' job satisfaction. However, these effects are indirect through the managers' perceptions of the fairness of these measures and the interpersonal trust these measures promote. Based on a sample of 70 managers, these expectations are supported by the results. More importantly, the results also suggest that (1) the process by which nonfinancial measures affect employee job satisfaction is not different from that of financial measures, and (2) the relative importance of nonfinancial measures vis-à-vis financial measures has no significant effect on employee job satisfaction. These results may have important theoretical and practical implications.     

The integrability of consumer demand functions

The purpose of this paper is to characterize the class of systems of consumer demand functions that are representable as ratios of first-order polynomial functions and are integrable. Starting from a general system of consumer demand functions representable as ratios, we impose successively the restrictions corresponding to homogeneity, summability, symmetry, non-negativity, and monotonicity. We find that the only such systems which are capable of modeling arbitrary own- and cross-substitution effects are the systems generated by transcendental logarithmic utility functions.     

Technological progress and technical efficiency in Chinese industrial growth: A frontier production function approach

We estimate a frontier production function for Chinese industry for the period 1953–1985. Contrary to prior studies based on OLS estimates, we find that Chinese industry has been characterized by a rate of growth of technological progress between 1.8 and 3.6 percent per year. We also find that the capital-saving nature of technological progress has adversely affected Chinese productivity growth because of increases in the capital-labor ratio. The utilization of industrial resources has been quite suboptimal for much of the sample period, with industrial production well off the production frontier. These deviations from efficient resource use reflect well-known political and economic developments that disrupted economic activity. Finally, both technical efficiency and total factor productivity increased appreciably in the period 1978–1985, suggesting that the reforms have had some positive impact on industrial performance.
