Authority and communication in the laboratory

We report findings from experiments on two delegation–communication games. An uninformed principal chooses whether to fully delegate her decision-making authority to an informed agent or to retain the authority and communicate with the agent via cheap talk to obtain decision-relevant information. In the game in which the delegation outcome is payoff-dominated by both the truthful and the babbling communication outcomes, we find that principal-subjects almost always retain their authority and agent-subjects communicate truthfully. Significantly more choices of delegation than of communication are observed in another game in which the delegation outcome payoff-dominates the unique babbling communication outcome; yet there is a non-negligible fraction of principal-subjects who holds on to their authority and agent-subjects who transmits some information. A level-k analysis of the game indicates that a principal-subject “under-delegates” due to the belief that her less-than-fully-strategic opponent will provide information; such belief is in turn consistent with the actual play.     

The flow-refueling location problem for alternative-fuel vehicles

Beginning with Hodgson (Geogr.Anal.22(1990) 270), several researchers have been developing a new kind of location-allocation model for “flow capturing.” Instead of locating central facilities to serve demand at fixed points in space, their models aim to serve demand consisting of origin-destination flows along their shortest paths. This paper extends flow-capturing models to optimal location of refueling facilities for alternative-fuel (alt-fuel) vehicles, such as hydrogen fuel cells or natural gas. Existing flow-capturing models assume that if a flow passes just one facility along its path, it is covered. This assumption does not carry over to vehicle refueling because of the limited range of vehicles. For refueling, it may be necessary to stop at more than one facility in order to successfully refuel the entire path, depending on the vehicle range, the path length, and the node spacing. The Flow Refueling Location Model (FRLM) optimally locates p refueling stations on a network so as to maximize the total flow volume refueled. This paper presents a mixed-integer programming formulation for the nodes-only version of the problem, as well as an algorithm for determining all combinations of nodes that can refuel a given path. A greedy-adding approach is demonstrated to be suboptimal, and the tradeoff curve between number of facilities and flow volume refueled is shown to be nonconvex.     

The valuation of multiple stock warrants

The issue of multiple series of stock purchase warrants by the same firm is an interesting financial structure not just in America, but is common in countries such as Switzerland, Malaysia, and Singapore. This paper derives valuation formulas for multiple series of outstanding warrants. The theoretical warrant prices from this model are compared against existing models. We report a subtle slippage effect and also a cross dilution effect that cause the existing models, such as Galai‐Schneller model, to be inappropriate for pricing such classes of multiple warrants. We also provide an example to illustrate the practicality of our model. The Greeks of the model are also derived in this paper. The complexity of multiple warrants could extend to other classes of contingent securities issued by the same firm but with differing expiry terms. © 2003 Wiley Periodicals, Inc.

The Baby Boom and the Stock Market Boom*

This paper addresses two issues. The first is whether demographic change was plausibly responsible for the run‐up in stock prices over the last decade, and whether an attempt by the baby boom cohort to cash out of its investments in the period 2010–2030 might lead to an “asset meltdown”. The second issue is whether the rise in dependency that will accompany the retirement of the baby‐boom cohort calls for an increase in national saving. We analyze these issues using a forward‐looking macro‐demographic model, and show that they are related via the existence of installation costs for capital. If such costs are sufficiently large, then demographics do have the power to affect stock prices, but “saving for America's old age” is less optimal. However, conventional estimates of capital installation costs are not large enough to explain large stock price movements in response to actual demographic change.     

The regional and global competitiveness of multinational firms

International competitiveness ultimately depends upon the linkages between a firm’s unique, idiosyncratic capabilities (firm-specific advantages, FSAs) and its home country assets (country-specific advantages, CSAs). In this paper, we present a modified FSA/CSA matrix building upon the FSA/CSA matrix (Rugman 1981). We relate this to the diamond framework for national competitiveness (Porter 1990), and the double diamond model (Rugman and D’Cruz 1993). We provide empirical evidence to demonstrate the merits and usefulness of the modified FSA/CSA matrix using the Fortune Global 500 firms. We examine the FSAs based on the geographic scope of sales and CSAs that can lead to national, home region, and global competitiveness. Our empirical analysis suggests that the world’s largest 500 firms have increased their firm-level international competitiveness. However, much of this is still being achieved within their home region. In other words, international competitiveness is a regional not a global phenomenon. Our findings have significant implications for research and practice. Future research in international marketing should take into account the multi-faceted nature of FSAs and CSAs across different levels. For MNE managers, our study provides useful insights for strategic marketing planning and implementation.     

Implications of Singapore's CPF Scheme on Consumption Choices and Retirement Incomes

Singapore has a unique policy of allowing the use of mandatory social security contributions to finance homeownership. An intertemporal model of housing demand is employed to demonstrate analytically that the CPF scheme can distort an individual's intertemporal and intratemporal consumption choices, and induce Singaporeans to demand more housing than they would otherwise. The withdrawals for housing have also affected the adequacy of CPF balances for financing retirement. Pegging the rate of return on CPF balances to a long‐term rate is the long‐term solution to curbing excessive withdrawals for housing, and ensuring the adequacy of CPF savings for financing retirement.     

Bank Interest Rate Adjustments: Are They Asymmetric?

This paper is concerned with the asymmetric adjustments between three Australian bank interest rates: a bank bill rate, a loan rate and a deposit rate. A multivariate asymmetric error-correction model is applied to capture the interplay of long-run relationships between the levels of the rates and short-run relationships between the changes in the rates. The empirical analysis, for the sample period 1990:01–2000:04, shows that interest rate adjustments, in response to positive and negative shocks, are asymmetric in the short run, but not in the long run. In particular, the results suggest that banks adjust their loan and deposit rates, in response to a change in the bank-bill rate, at a faster rate during periods of monetary easings (negative changes) than during periods of monetary tightenings (positive changes).
