Efficiency in the international insurance industry: A cross-country comparison

The purpose of this paper is to provide new empirical evidence on frontier efficiency measurement in the international insurance industry, a topic of great interest in the academic literature during the last several years. A broad efficiency comparison of 6462 insurers from 36 countries is conducted. Different methodologies, countries, organizational forms, and company sizes are compared, considering life and non-life insurers. We find a steady technical and cost efficiency growth in international insurance markets from 2002 to 2006, with large differences across countries. Denmark and Japan have the highest average efficiency, whereas the Philippines is the least efficient. Regarding organizational form, the results are not consistent with the expense preference hypothesis, which claims that mutuals should be less efficient than stocks due to higher agency costs. Only minor variations are found when comparing different frontier efficiency methodologies (data envelopment analysis, stochastic frontier analysis).     

The performance of hedge funds and mutual funds in emerging markets

Use of short selling and derivatives is limited in most emerging markets because such instruments are not as readily available as they are in developed capital markets. These limitations raise questions about the value added provided by hedge funds, especially compared to traditional mutual funds active in these markets. We use five existing performance measurement models plus a new asset-style factor model to identify the return sources and the alpha generated by both types of funds. We analyze subperiods, different market environments, and structural breaks. Our results indicate that some hedge funds generate significant positive alpha, whereas most mutual funds do not outperform traditional benchmarks. We find that hedge funds are more active in shifting their asset allocation. The higher degree of freedom that hedge funds enjoy in their investment style might thus be one explanation for the differences in performance.     

A High‐Frequency Investigation of the Interaction between Volatility and DAX Returns

One of the most noticeable stylised facts in finance is that stock index returns are negatively correlated with changes in volatility. The economic rationale for the effect is still controversial. The competing explanations have different implications for the origin of the relationship: Are volatility changes induced by index movements, or inversely, does volatility drive index returns? To differentiate between the alternative hypotheses, we analyse the lead‐lag relationship of option implied volatility and index return in Germany based on Granger causality tests and impulse‐response functions. Our dataset consists of all transactions in DAX options and futures over the time period from 1995 to 2005. Analyzing returns over 5‐minute intervals, we find that the relationship is return‐driven in the sense that index returns Granger cause volatility changes. This causal relationship is statistically and economically significant and can be clearly separated from the contemporaneous correlation. The largest part of the implied volatility response occurs immediately, but we also observe a smaller retarded reaction for up to one hour. A volatility feedback effect is not discernible. If it exists, the stock market appears to correctly anticipate its importance for index returns.     

Do foreign institutional investors destabilize China’s A-share markets?

This paper investigates the effect of foreign institutional investors on the stability of Chinese stock markets. Previous literature views this investor group as destabilizing feedback traders. We use the abolition of ownership restrictions on A shares as a natural experiment. There is strong evidence that foreign institutions have a stabilizing effect on Chinese stock markets and contribute to market efficiency. This finding is robust across exchanges, sample periods, size quintiles and alternative model specifications. By contrast, domestic investors appear to engage in positive feedback trading. Our results have important implications for market regulation.     

Why Do the Swiss Rent?

At less than 34%, Switzerland has the lowest home ownership rate in Western Europe. This may seem odd given the economic strength of the country. We use household survey data for five Swiss cantons to explore some possible reasons for this. We estimate a tenure choice equation that allows us to analyze the impacts of a number of key variables on the ownership rate. We pay particular attention to the relative cost of owning and renting, which is a function of house prices, rents, and the user cost of owning. The latter is a function of income tax policy and expected house price inflation, among other things. We also measure mortgage underwriting criteria and consider rent control and other policies affecting rental housing. By simulating a number of hypothetical changes to taxation and other policies, underwriting criteria, and price levels, we assess the importance of these variables in explaining the ownership rate. We conclude that high house prices—relative to household incomes and wealth—and the tax on imputed rent are the most important causes of Switzerland’s low ownership rate.     

Going short‐term or long‐term? CEO stock options and temporal orientation in the presence of slack

Research summary: We draw on behavioral agency theory to explain how decision heuristics associated with CEO stock options interact with firm slack to shape the CEO's preference for short‐ or long‐term strategies (temporal orientation). Our findings suggest CEO current option wealth substitutes for the influence of slack resources in encouraging a long‐term orientation, while prospective option wealth enhances the positive effect of slack on temporal orientation. Our theory offers explanations for non‐findings in previous analysis of the relationship between CEO equity based pay and temporal orientation and provides the insights that CEO incentives created by stock options (1) enhance the effect of available slack upon temporal orientation and (2) can both incentivize and de‐incentivize destructive short‐termism, depending upon the values of current and prospective option wealth. Managerial summary: We explore how compensation design can play a role in affecting the CEO's preference for short‐ or long‐term strategic projects. When the CEOs have accumulated option wealth, they are more likely to invest in the long term. Yet when they have a large number of recently granted options with the potential to generate significant wealth in the event of successful risk taking, the CEO is more likely to prefer the short term in order to achieve personal wealth gains more quickly. The more liquid assets the firm holds, the weaker both of the aforementioned effects. An implication for boards is that they should anticipate CEO short‐termism if the CEO has been granted new options, underlining the potential negative consequences of option compensation.

Reconciling Gray and Hotelling

A bstract .   Early exhaustible resource economics provides an important foundation for recent suggestions that firm-level economic modeling plays a larger role in the analysis of resource scarcity. The lack of empirical support for Hotelling's r -percent rule, introduced in 1931, and recent suggestions that industry behavior may not be reducible to firm behaviors are the primary motivating factors for examining the relative value of Gray's contribution to the field of exhaustible resource economics relative to Hotelling's contribution. Specifically, Gray's papers that appeared in the 1910s provide insight into the heterogeneity of deposits and their spatial dimensions, and offer the possibility that firms will be subject to fixed costs carried over between periods. In this paper, the arguments presented by Gray are formalized in a dynamic model, which allows the differences between Gray's and Hotelling's assumptions to be more fully explored. The results of the paper illustrate that by considering spatially identifiable heterogeneous deposits, fixed costs, and entry costs, in general Hotelling's r -percent rule is not a sufficient condition for firm-level decision making and that firms' extraction behavior cannot be linearly aggregated to describe industry behavior.     

Is there a bigger and better future for employer branding? Facing up to innovation,corporate reputations and wicked problems in SHRM

Employer branding is becoming an increasingly important topic for research and practice in multinational enterprises (MNEs) because it plays directly into their corporate reputation, talent management and employee engagement agendas. In this paper, we argue that the potential effects of employer branding have yet to be fully understood because current theory and practice have failed to connect this internal application of marketing and branding to the key reputational and innovation agendas of MNEs, both of which are at the heart of another strategic agenda – effective corporate governance. However, these agendas are characterised by ‘wicked problems’ in MNEs, which have their origins in competing logics in strategic human resource management (SHRM). These problems need to be articulated and understood before they can be addressed. This paper proceeds by (1) setting out a definition and model of employer branding and how it potentially articulates with corporate governance, innovation and organisational reputations, (2) discussing and analysing the ‘wicked problems’ resulting from the sometimes contradictory logics underpinning innovation and corporate reputations and SHRM in MNEs and (3) evaluating the potential of employer branding as a contribution to the third SHRM approach – HR strategy-in-action – as a way of resolving three particularly wicked problems in MNEs. We conclude with some ideas for research and practice on the future for employer branding.
