MEASURING LIMITS OF ARBITRAGE IN FIXED‐INCOME MARKETS

An emerging literature relies on an index of limits of arbitrage in fixed‐income markets. We analyze the benefits of an index that is model‐free, robust, and intuitive. This new index strengthens the evidence that limits of arbitrage proxy for risks priced in the cross‐section of returns. Trading simulations show that the new index improves identification of limits of arbitrage because it bypasses a noisy estimation step. Relative value indices in the United States, United Kingdom, Japan, Germany, Italy, France, Switzerland, and Canada exhibit strong commonality and high correlations with local volatility and funding conditions. The indices are updated regularly and available publicly.

A Study of the Attitude toward Convergent Products: A Focus on the Consumer Perception of Functionalities

The convergent product is an increasingly important phenomenon in the marketplace. The convergent product allows the developer to include more and more diverse functionalities into their products, which can satisfy a broad range of consumer needs. However, failures of convergent products arouse the need to understand its functionalities, and the optimal combination of functionalities and their relationships to attitude and purchase intention. In addition, because convergent product has the potential to offer more diverse functionality, we consider if this will have impacts on instrumental and emotional needs fulfillment and attitude and purchase intention. Additionally, consumer innovativeness was examined to ascertain if there were differences among consumers on their classification of the functionalities, or if it will moderate functional diversity, needs fulfillment, and product attitude. Using the Kano model, this study examined the nature of these relationships by examining the functionalities of a smartphone. Overall, our results show that the convergent products that include functionalities from two of the three categories of the Kano model, must‐have and attractive, were rated more positively. Consumer innovativeness differences were found. Consumers with high innovativeness considered must‐have and one‐dimensional functionalities the most important, and consumers with low innovativeness considered all three important, although one‐dimensional functionalities were considered significantly less important. Although increasing functional diversity positively raises product attitude and purchase intention, it tends to raise emotional needs fulfillment only once instrumental needs have been met, especially for respondents showing low innovativeness. The findings should arouse interest about factors that should not be overlooked when developing new convergent products.     

DIFFERENTIAL RISK‐TAKING IMPLICATIONS OF PERFORMANCE INCENTIVES FROM STOCK AND STOCK OPTION HOLDINGS

We study the risk‐taking implications of managerial pay‐for‐performance incentives (delta) arising from stock and stock options separately in the United States between 1992 and 2017. The current literature assumes that each unit of delta has an equal incentive effect on firm performance. Instead, we show that the risk‐reducing effect of performance incentives is more pronounced for executives whose delta comes mostly from stock holdings relative to option holdings. Accordingly, we propose a new measure that takes into account the magnitude of delta from option holdings relative to delta from stock holdings (source ratio). Our results show that risk taking increases as this ratio increases.

Offshoring Professional Services: Institutions and Professional Control

We examine the reasons why one might expect it to be more difficult to offshore professional work than manufacturing work in a globalized world. We then provide data on the variations in a specific case — the offshoring of diagnostic radiology from the USA, UK and Singapore. We show that existing theories on the ‘offshorability’ of jobs have not captured how national institutions and occupational regulations continue to define professional work. We then review the question of supply from India's perspective and report that both macro‐institutional and organizational contexts make it complicated for Indian doctors to supply much of this service.     

Consumption-based CAPM models: International evidence

We examine the performance of several types of the consumption-based CAPM (C-CAPM) models to explore if consumption factors matter for determining excess returns across 17 MSCI country indexes. While the classic world C-CAPM does exhibit some power in explaining cross-sectional variations of expected excess returns, the model seems to require an implausibly large coefficient of risk aversion. The more sophisticated models including the heterogeneous C-CAPM, the world surplus consumption and the habit-formation models provide more reasonable estimates and add substantial explanatory power for the variation in the cross section of excess stock returns. Our results suggest that country-specific consumption risk is not fully diversified thus implying that stock returns are related to idiosyncratic consumption risk.     

Is China’s Manufacturing Industry Efficient? Evidence from an Energy-Rebound Effect Perspective

Majority of the increase in global energy consumption is from China; hence, studying energy issues, especially in China’s manufacturing industry (CMI), is worthwhile and of much interest in the academic field. Based on the translog cost function, we develop a research framework to study the rebound effect of CMI. Considering the effect of asymmetric energy price, we augment the energy-cost function with asymmetric influence constraint of energy price. Again, we add time series data of CMI’s capital, labor, energy, and mid-input to the model to calculate the direct rebound effect of CMI. We find that the rebound effect of CMI is 44.2%, and CMI still has large energy-conservation potentials. Based on the results of this study, some policy recommendations are provided.
