Allocation,externalities, and building value

Externalities generally are viewed as impacting land values rather than building values. Yet when locational obsolescence is attributed to externalities, the implication is that externalities impact primarily on building values. The presence of negative externalities generally does not determine whether a building suffers from locational obsolescence; the more general cause is a misallocation of land. At the market allocation, there is no locational obsolescence even in the presence of an externality, while at the optimal allocation only an externality can produce locational obsolescence. Because locational obsolescence can exist without externalities, an externality is not a necessary condition for locational obsolescence. Because an externality can be present without accompanying locational obsolescence, an externality also is not a sufficient condition for the existence of locational obsolescence.     

The greening of Swedish energy policy: A critique

This article discusses Swedish energy policy over the period 1973–1992 with a focus on its current energy objectives. Bans on energy sources are assessed as one of the challenges faced by Sweden in the 1990s. We raise questions about the future consequences of such draconian approaches to energy policy that inhibit societal learning. Bans on any fuel source only serve to handicap the economy and lead to a less flexible and more inefficient energy supply at a greater than necessary cost. With the Swedish economy on the verge of becoming more integrated with the rest of Europe, it is imperative to view its comparative advantage in electricity as the basis for its energy policy rather than the individual fuels that generate that electricity. Our goal has been to synthesize components among existing energy objectives to suggest logical implications for the future.     

A Nonparametric Approach to Pricing and Hedging Derivative Securities Via Learning Networks

We propose a nonparametric method for estimating the pricing formula of a derivative asset using learning networks. Although not a substitute for the more traditional arbitrage-based pricing formulas, network-pricing formulas may be more accurate and computationally more efficient alternatives when the underlying asset's price dynamics are unknown, or when the pricing equation associated with the no-arbitrage condition cannot be solved analytically. To assess the potential value of network pricing formulas, we simulate Black-Scholes option prices and show that learning networks can recover the Black-Scholes formula from a two-year training set of daily options prices, and that the resulting network formula can be used successfully to both price and delta-hedge options out-of-sample. For comparison, we estimate models using four popular methods: ordinary least squares, radial basis function networks, multilayer perceptron networks, and projection pursuit. To illustrate the practical relevance of our network pricing approach, we apply it to the pricing and delta-hedging of S&P 500 futures options from 1987 to 1991.     

Bank Capital and the Credit Crunch: The Roles of Risk-Weighted and Unweighted Capital Regulations

We investigated whether in recent years banks have increased their holdings of securities at the expense of their holdings of business loans in response to shortfalls of their capital relative to risk-weighted capital standards and relative to a capital standard that made no explicit allowance for credit risk. We estimated that bank credit fell by about $4.50 for each $1 that a bank's capital fell short of the unweighted capital standard. Banks that had less capital than required by the risk-weighted standard appear to have shifted away from assets with low risk weights (securities and single-family mortgages) and to have shifted toward assets with higher risk weights (commercial real estate and commercial and industrial loans). When we included both shortfall variables in a regression, shortfalls relative to the unweighted capital standard significantly affected bank credit, while shortfalls of capital relative to the risk-weighted standard did not. We found no significant effects of capital shortfalls at other, local-competitor banks on bank portfolios. Delinquencies in a given category of a bank's loans generally had significantly negative effects on that bank's holdings of loans in that category. In contrast, banks tended to increase holdings of loans in categories in which local-competitor banks were experiencing higher delinquency rates.     

Waiting to Default: The Value of Delay

This paper analyzes the opportunity for early termination of a mortgage contract. We consider the possibility of defaulting on the property and explore the rules that are used by a value-maximizing borrower in exercising this option to default. The discussion centers on the value of waiting to make such a decision and the consequences of this rational inertia. We show that the observed delay in default usually attributed to transaction costs can instead be explained as entirely rational choice in a dynamic environment.     

How industrial salespeople gain customer trust

This study investigated how industrial salespeople gain the trust of their customers. Results show that trust increases as the customer gains the impression that the salesperson is dependable, honest, competent, customer oriented, and likeable. Based on the results, a general model of trust building is suggested.     

Resource flows through the multilateral system for food and agriculture : Trends of the decade

The tenth session of the World Food Council in Addis Ababa, Ethiopia, held on 11–15 June 1984, undertook an assessment of international activities in the decade since 1974 for meeting the World Food Conference objectives of improving the global food system and overcoming the blight of world hunger. One document prepared for the session looks specifically at the activities of the multilateral institutions since the 1974 conference, in terms of both resource and programme commitments. This article provides a summary of that WFC document.     

Key problems facing industrial distributors

This article reports on a survey of the problems faced by industrial distributors. Five major problem categories are identified and managerial implications are derived from the findings.
