Fire department demand and supply in large cities

The purpose of this study is to estimate demand and production functions for fire fighters provided in major cities. Several factors, including the level of fire losses in the communityper capitaincome, relative wages of fire fighters, population density, city size, and poverty are used in the analysis.

This study differs from earlier ones in two ways. First, multiple measures of community fire losses, instead of the usual one, are used in the analysis. Second, in contrast with earlier studies of fire protection which have typically relied on ordinary least squares regression analysis (OLS) to study either demand or production, this study employs two stage least squares regression analysis (2SLS) to simultaneously estimate demand and production relations.

Evidence is found that demand for fire fighting is affected by both fire losses and relative size of per capitaincome to fire fighter wages. Losses, in turn, are affected by fire fighting hours, by poverty and by density. There is some evidence for economies of scale. The results were consistently found for the variety of loss measures used. The 2SLS results indicated that, as expected, there are simultaneous effects occurring in demand and supply.     

Asia-pacific finance and investment: a case study of taiwan

The present research design adopts the dual instruments of the mail-survey questionnaire and the interview. The research was aimed at deriving an objective function of an Asia-Pacific finance and investment model of the Republic of China in the twenty-first century. The objective function consists of three types of policy or strategic variables pertinent to economic achievement, global finance and investment strategy, the macro-impact on international finance and investment. Another purpose of this study was to confirm three hypotheses qualitatively through empirical findings.     

Smoke-filled Rooms and Research: A Response to Jean J. Boddewyn's Commentary

Abstract

Professor Boddewyn's discussion raises important issues about the social importance and objectivity of academic research. One major issue concerns the social relevance of the advertising research conducted by academics, which Professor Boddewyn contends is largely neglected by the mass media. This neglect “renders main-line advertising scholars irrelevant.”     

The Introduction of a Non-Traditional and Aggressive Approach to Banking: The Risks of Hubris

This study integrates institutional theory and social cognitive theory to describe how peripheral organizations can accidentally bring about radical change even in highly institutionalized and change-resistant fields. The empirical context is the field of banking in Ireland (1995–2001), where a peripheral bank triggered a shift away from traditionally conservative and risk-averse banking values toward aggressive values of entrepreneurial risk taking. The introduction of a new approach to banking was attributed to three factors: (1) a benevolent environment, which made this innovation feasible and timely, (2) the state of the field, which had gaps that could be addressed through specialization, and (3) prior successes, which created hubris in the senior managers, thereby increasing the pace and scope of adoption of this approach. Eventually, what started as a specialized and entrepreneurial approach led to the spread of a risky approach to banking across the entire field. The study highlights the risks of hubris, in that media praise and early successes can increase the pace of adoption of innovations which offer short-term gains but are detrimental in the long term.     

Route-based data envelopment analysis models

This paper proposes two novel route-based data envelopment analysis (DEA) models that jointly measure the route-level and company-level efficiencies amongst transport carriers. The core logics comprise a three-stage procedure that determines company efficiency, route efficiency and optimal allocation ratios for the common inputs. We prove that the ranking order of company performance determined by the route-based DEA model is identical to that determined by the company-based DEA model. An empirical case demonstrates the superiority of the proposed models in identifying the less efficient routs/companies as well as in reducing the input slacks without subjective conjectures.     

Trading networks with price-setting agents

In a wide range of markets, individual buyers and sellers trade through intermediaries, who determine prices via strategic considerations. Typically, not all buyers and sellers have access to the same intermediaries, and they trade at correspondingly different prices that reflect their relative amounts of power in the market. We model this phenomenon using a game in which buyers, sellers, and traders engage in trade on a graph that represents the access each buyer and seller has to the traders. We show that the resulting game always has a subgame perfect Nash equilibrium, and that all equilibria lead to an efficient allocation of goods. Finally, we analyze trader profits in terms of the graph structure — roughly, a trader can command a positive profit if and only if it has an “essential” connection in the network, thus providing a graph-theoretic basis for quantifying the amount of competition among traders.     

Lawyers and medical torts: medical malpractice litigation as a residual option

The relationship between the supply of lawyers and the frequency of medical malpractice claims for one state is examined. A model of the location decisions of lawyers within a state developed. These decisions depend on their forecasts of the amounts of various types of legal business which will be available. Because such forecasts are inperfect, however, at a given time an excess of lawyers in any given hypothesized, there will then be an incentive to dip deeper into the available pool of malpractice cases. This hypothesis is tested and it is found that the estimated excess of lawyers over those required to perform other tasks is a significant factor in explaining the filing of malpractice claims.     

An Empirical Investigation of the Campbell-Cochrane Habit Utility Model

Abstract:  This paper tests whether the Campbell and Cochrane (1999) habit utility model generates a valid stochastic discount factor for the 25 Fama-French size/book-to-market and size/momentum sorted portfolios. Campbell and Cochrane (1999) derive a consumption based habit utility asset pricing model and calibrate it to aggregate US stock market data. However, they do not test whether their model is consistent with a larger cross section of asset returns. We test their model using the methodology of Hansen and Jagannathan (1991) and Burnside (1994) . In contrast to previous studies, we find that for reasonable parameter values, the model's stochastic discount factor is inside the Hansen-Jagannathan bounds and therefore satisfies the necessary conditions for a valid stochastic discount factor. We trace the difference between our results and previous studies to the method used to estimate the model's parameters and the parameter values themselves.     

Productivity,the Terms of Trade,and the Real Exchange Rate: Balassa–Samuelson Hypothesis Revisited

The paper examines how the Balassa–Samuelson hypothesis is affected by a modern variation of the standard model that allows product differentiation (within the traded and nontraded goods sectors) with the number of firms determined exogenously or endogenously. The hypothesis is found to be fragile in the modified framework. Small variations in the elasticity of substitution between home and foreign traded goods (within the range of estimates suggested in the literature), for example, can make the effect of a traded‐goods productivity improvement on the real exchange rate negative or positive, as well as small or large. This result provides a potential explanation of the mixed empirical results that have been obtained on the relationship between productivity and the real exchange rate.
