Model uncertainty and liquidity

Extreme market outcomes are often followed by a lack of liquidity and a lack of trade. This market collapse seems particularly acute for markets where traders rely heavily on a specific empirical model such as in derivative markets like the market for mortgage backed securities or credit derivatives. Moreover, the observed behavior of traders and institutions that places a large emphasis on “worst-case scenarios” through the use of “stress testing” and “Value-at-Risk” seems different than Savage expected utility would suggest. In this paper, we capture model-uncertainty using an Epstein and Wang [Epstein, L.G., Wang, T., 1994. Intertemporal asset pricing under Knightian uncertainty. Econometrica 62, 283–322] uncertainty-averse utility function with an ambiguous underlying asset-returns distribution. To explore the connection of uncertainty with liquidity, we specify a simple market where a monopolist financial intermediary makes a market for a propriety derivative security. The market-maker chooses bid and ask prices for the derivative, then, conditional on trade in this market, chooses an optimal portfolio and consumption. We explore how uncertainty can increase the bid–ask spread and, hence, reduces liquidity. Our infinite-horizon example produces short, dramatic decreases in liquidity even though the underlying environment is stationary. We show how these liquidity crises are closely linked to the uncertainty aversion effect on the optimal portfolio. Effectively, the uncertainty aversion can, at times, limit the ability of the market-maker to hedge a position and thus reduces the desirability of trade, and hence, liquidity.     

Auctioning Immigration Visas

Freeman (2006 ) suggested that auctioning immigration visas and redistributing the revenue to native residents in the host country would increase migration from low-income to high-income countries. The effect of the auctioning of immigration visas, in the Ricardian model from Findlay (1982 ), on the optimal level of immigration for the host country is considered. It is shown that auctioning immigration visas will lead to a positive level of immigration only if the initial wage difference between the host country and the source country is substantial. The cost of the immigration visa is more than half the earnings of the immigrant worker.     

The Effects of Executive,Firm, and Board Characteristics on Executive Exit

We estimate a hazard model of the probability of top corporate executives exiting their firms over the period 1996–2010. Our main findings are that: (1) female executives have greater likelihoods of exit than males, (2) the likelihood of exit increases with the independence of the board and decreases with the fraction of the board that is female and the average age of board members, and (3) a higher percentage of independent directors on the board lowers the probability of exit more for females than for males. Further, controlling for exit risk reduces the well‐documented compensation differential between men and women.     

Can pure play internet banking survive the credit crisis?

This paper positions the pure-play internet banking model (PPI) as a hybrid business model that combines features of both relationship and transaction banking. Although in terms of customer orientation PPI banks may partly resemble relationship banks, they lack their comparative advantage in generating borrower-specific information. Instead, the characteristic features of PPI banks are low costs and easy scalability. While the latter may enable PPI banks to quickly capture market share, it may also generate overexposure in risky markets. We present a case study on ING Direct, one of the leading global PPI banks and address the sustainability of the PPI business model by comparing the ING Direct foreign operations. The findings for ING Direct are validated using data for E-Trade Bank. We conclude that managing growth appears to be the prime challenge to PPI banks.     

Enterprise Risk Management and the Cost of Capital

Enterprise risk management (ERM) is a process that manages all risks in an integrated, holistic fashion by controlling and coordinating any offsetting risks across the enterprise. This research investigates whether the adoption of the ERM approach affects firms' cost of equity capital. We restrict our analysis to the U.S. insurance industry to control for unobservable differences in business models and risk exposures across industries. We simultaneously model firms' adoption of ERM and the effect of ERM on the cost of capital. We find that ERM adoption significantly reduces firm's cost of capital. Our results suggest that cost of capital benefits are one answer to the question how ERM can create value.     

The sales recovery audit: Learning to walk the talk

Little research attention has been devoted to the impact of salesperson failure and recovery management on customer relationship development. This paper develops a theoretically anchored and externally validated sales recovery audit for the purpose of assessing sales organization performance in these matters. Results based on a survey of 177 sales managers indicate that practice of sales recovery efforts lags behind their perceived importance as they relate to organizational success. The sales recovery audit presented here can be a useful tool to continuously evaluate and enhance sales recovery efforts for the purpose of building a stronger relationship selling organization.     

Uncertainty in the transaction environment: an empirical test

Previous studies examining the relationship between uncertainty and vertical integration have produced a conflicting set of results. To clarify this puzzle we drew on the literature to conceptualize three distinct forms of uncertainty—primary, competitive, and supplier—and hypothesized that each had a different effect on vertical integration. The hypotheses were tested using experimental data collected from 308 managers. Consistent with our prediction of differential effects, we found that primary and competitive uncertainty were negatively associated with the decision to vertically integrate, but supplier uncertainty was positively related to the vertical integration decision. No interaction effects were found. Implications for theory and research are suggested. © 1998 John Wiley & Sons, Ltd.     

Assessing supply chain risks with the analytic hierarchy process: Providing decision support for the offshoring decision by a US manufacturing company

This paper reports the process used by a US manufacturing company to assess supply chain risks within the context of an offshore sourcing decision. The case study company was faced with the objective of finding a new supplier for two of its major product lines. Five alternatives were considered: (1) sourcing finished goods from Mexico; (2) sourcing finished goods from China; (3) sourcing parts from China and assembly in the US; (4) sourcing parts from China, assembly in a Maquiladora in Mexico with investment; and (5) sourcing parts from China, assembly in a Maquiladora in Mexico with no investment in the venture. To find the best solution, action research methodology was combined with the application of the analytic hierarchy process (AHP). Through iterative and structured discussions, 17 risk factors were identified, which were subsequently grouped into main and sub objectives. AHP was then used to evaluate the importance of each risk factor, and to determine the best alternative. This study makes several contributions to the field of purchasing and supply management. First, it provides a comprehensive framework of empirically derived risk factors to be considered in an international sourcing context. Second, it shows how AHP can be used to assess these risk factors and alternatives as part of the framework to facilitate and support the final offshoring decision. And third, it illustrates the successful application of the approach by a US manufacturing company. As such, this paper contributes to the research streams of offshoring and risk management in purchasing and supply, as well as to decision-making under uncertainty and AHP. In addition, it serves as a practical methodology for firms in similar situations.
