How Persistent is Stock Return Volatility? An Answer with Markov Regime Switching Stochastic Volatility Models

Abstract:  We propose generalised stochastic volatility models with Markov regime changing state equations (SVMRS) to investigate the important properties of volatility in stock returns, specifically high persistence and smoothness. The model suggests that volatility is far less persistent and smooth than the conventional GARCH or stochastic volatility. Persistent short regimes are more likely to occur when volatility is low, while far less persistence is likely to be observed in high volatility regimes. Comparison with different classes of volatility supports the SVMRS as an appropriate proxy volatility measure. Our results indicate that volatility could be far more difficult to estimate and forecast than is generally believed.     

Closure and divestiture by foreign entrants: the impact of entry and post‐entry strategies

We analyze the longevity of foreign entrants explicitly considering two possible ways of exit: firm closure and capital divestiture. We find that entry and post‐entry strategies affect the longevity of firms and of foreign equity holdings, but in different manners. While the ownership arrangements and organizational structure affect the likelihood of divestment, they exert no significant effect upon closure. The entry mode exerts opposite effects on the two modes of exit, greenfield entrants being more likely to shutdown, but less likely to be divested. Only human capital affects closure and divestment in the same manner. Firms with large endowments of human capital are less likely to exit, irrespective of the exit mode considered.

Ways to improve pioneer new ventures' performance in the ICT industry

This paper analyses how marketing capabilities and low cost orientation improve the performance obtained by technology new ventures that enter the market early. In a sample of 104 new ventures of the Information and Communications Technology (ICT) industry, the authors have developed a regression analysis allowing them to demonstrate the direct and indirect effects proposed in the hypotheses. The results obtained show that early entry into the market has a positive influence on new venture performance, as the joint moderator effect of marketing capabilities and low cost orientation is greater than the effect of each variable taken on its own. Furthermore, this study explores if the effects of the analysed factors are different between telecommunications and electronic and computer new ventures. This study shows that marketing capabilities and low cost strategy are complements rather than substitutes in moderating the relationship between entry timing and new venture's performance, especially for the telecommunications new ventures.     

Determinants of Web 2.0 technologies for knowledge sharing in SMEs

Web 2.0 technologies are increasingly being used within all knowledge management processes. This paper extends previous studies on the use of internet technologies and knowledge management by analyzing factors affecting knowledge sharing through Web 2.0 technologies within small and medium-sized enterprises (SMEs). Drawing upon the technology-organization-environment framework, a model is developed to examine how distinct contextual factors influence the use of Web 2.0 technologies for knowledge sharing. A data set of Spanish SMEs is used to test the conceptual model and hypotheses. Results show that knowledge sharing through Web 2.0 technologies emerges from internal organizational and technological resources rather than from external pressure.     

Business ethics and business education: A report from a regional state university

My central point is that the recent wave of interest in business ethics is an opportunity to review the whole enterprise of undergraduate business education. Business ethics, taught as if the students, faculty, curriculum and organization of the business school were important parts of the subject matter, is a way both to affirm the seriousness of ethical inquiry and to build an increased sense of collegial responsibility for the overall curriculum students are asked to undertake. Barry Castro is Professor of Management and Assistant Dean at the Seidman School of Business at Grand Valley State University in Allendale, Michigan. His papers have been published in the American Economic Review, The Journal of Political Economy, The Harvard Educational Review, Change, and Soundings.     

The effect of oil price on China's exports

The increase in oil prices in recent years has occurred concurrently with a rapid expansion of Chinese exports in the world markets, despite China being an oil importing country. In this paper we develop a theoretical model that explains the positive correlation between Chinese exports and the oil price. The model shows that Chinese growth can lead to an increase in oil prices that has a stronger impact on its export competitors. This is due to the large labor force surplus of China. We then examine this hypothesis by estimating a reduced form equation for Chinese exports using Rodrik [Rodrik, Dani, 2006. What's so special about China's exports? China and World Economy 14, 1–19.]'s measure of export competitiveness, together with the oil price, productivity, real exchange rate, and foreign industrial production over the monthly 1992–2005 period. The results suggest a stable relationship and yields slightly positive values for the price of oil and elastic coefficients for export competitiveness, along with the expected negative elasticity for the real exchange rate.

Exchange Rates,Employment and Labour Market Rigidity

In this paper, we study the effect of labour market rigidity on the impact of exchange rate shocks on employment. We use a panel dataset comprising 22 manufacturing sectors across 23 OECD countries. In our econometric model, the impact of exchange rate fluctuations on sectoral employment is mediated by the degree of openness and by a measure of labour market rigidity: the OECD's employment protection legislation (EPL) index. Our results suggest that greater labour market rigidity reduces the impact of exchange rate shocks on employment. This effect is statistically significant for low‐technology sectors.     

Salesperson CLV orientation's effect on performance

Previous studies show how strategies based on the customer lifetime value (CLV) can lead to an increase of profitability for a firm. In this context, marketing serves the purpose of maximizing CLV and customer equity (the CLV of current and future customers). For most types of service firms, salespeople are direct participants in implementing the CLV concept. However, prior research does not answer the question of whether or how salesperson CLV orientation can enhance profits. Using data on salespeople in a large Chilean retail bank, this study shows that the effect of salesperson CLV orientation on salesperson performance follows an S-shaped function (which is first convex and then concave). Additionally, data does not support the idea that the optimum level of CLV orientation depends on salesperson customer orientation, salesperson adaptive selling behavior, or salesperson experience (i.e., CLV-oriented behaviors could be effective across a wide range of salespeople). As such, this study addresses an important concern among researchers and managers that is related to how to increase the salesperson performance. The findings of this study suggest that firms need to monitor individual salesperson CLV orientation more closely.     

Monitoring, reputation and accountability in issuing banks in mid-nineteenth-century Spain

This paper analyses the determinants of issuing banks' disclosure in the mid-nineteenth century in Spain. Our theses are that the State was the main promoter of accountability because of the public interest in the financial sector, and that banks used disclosure to gain and maintain reputation among their stakeholders in order to facilitate the circulation of their notes. This led to a high level of compliance with regulation, except in the crisis period of 1866–68, and to an increase in voluntary disclosure in bigger banks and in those that received security deposits, which were considered at this time to be a sign of reputation.
