Telecommunications Investment and Traffic in Developing Countries: The Effects of International Settlement Rate Reforms

In 1997 the FCC ordered sharp decreases in international settlement rates (bilaterally negotiated telecommunication rates) between the U.S. and other countries. Developing countries, which received about $35 billion in net settlement payments from U.S. carriers between 1985 and 1998, claim that payments finance telecom investment and that reduced rates, and therefore payments, will harm investment. Using a panel dataset of 179 countries from 1985–1998, I find settlement rates negatively correlated with international telecom traffic, suggesting that reduced rates will stimulate traffic. I also find no evidence that payments finance investment as measured by telephone penetration and telecommunications equipment imports.     

Modifying Conjoint Methods to Model Managers' Reactions to Business Environmental Trends: An Application to Modeling Retailer Reactions to Sales Trends

This article proposes and demonstrates how conjoint methods can be adapted to allow the modeling of managerial reactions to various changes in economic and competitive environments and their effects on observed sales levels. Because in general micro-level data on strategic decision making over time are difficult and expensive to obtain, this approach can be of much value to the further study of managerial strategic behavior and market dynamics. In our application we model retailer reactions to changes in their sales, focusing in particular on the actions that affect the demand for retail space and possibilities to improve retail sites. Choice responses to hypothetical sales and environmental trend scenarios are collected from 183 retailers and used to estimate to logit regression model that predicts retailers' probabilities of choosing actions. The model results confirm that retailers are more likely to take action when sales go down than when they go up, and also that they react more quickly if sales go down. It is also found that retailers are more reluctant to change the positioning of their store when confronted with a sales increase than when confronted with a sales decrease. The model is compared with a non-experimental model that is based on retailers' reactions to the trends they report to have observed for their own stores. The article concludes with a discussion of the implications of this research for the further development of conjoint-like approaches to studying entrepreneurial behavior.     

Empirical research on the resource‐based view of the firm: an assessment and suggestions for future research

The resource‐based view (RBV) is one of the most widely accepted theories of strategic management. However, to date no systematic assessment of the RBV's level of empirical support has been conducted. In response, a sample of RBV‐grounded empirical articles was analyzed from which it was found that the RBV has received only modest support overall and that this support varies considerably with the independent variable and theoretical approach employed. It is therefore suggested that scholars avoid the tendency to test models reflecting early incarnations of the RBV and instead test those that incorporate its more contemporary theoretical extensions.

Pesticide productivity,host-plant resistance and productivity in China

Pesticides are used as the primary method of pest controf in Asian rice production. Conditions in China have led to demand for high and increasing rice yields, resulting in intensive cultivation and adoption of fertilizer responsive varieties. The consequence has been widespread pest infestations. Many studies have estimated pesticide productivity, but few have estimated the productivity of alternative methods ot pest control, namely host-plant resistance. None have estimated the substitutability between these methods of pest-control. The productivity of pesticides and host-plant resistance, and the substitutability between them is measured using two-stage Cobb-Douglas and translog production functions. Under intensive rice production systems in eastern China, pesticide productivity is low compared to the productivity of host-plant resistance. In fact, returns to pesticide use are negative at the margin. Host-plant resistance is an effective substitute for pesticides and substantial reductions in pesticide use could be achieved, with no loss in rice production, through improvements in host-plant resistance. These results suggest that pesticides are being overused in eastern China and host-plant resistance is being underutilized. Government policies to promote increased pesticides in rice might be ill advised given the low productivity and negative returns, particularly in light of well known negative externalities associated with pesticide use.     

Family Members' Projections of Each Other's Preference and Influence: A Two-Stage Conjoint Approach

Two important sources of error that may limit the accuracy of individual family members' projections of joint family preferences are: (i) misperceptions of other members' preferences, and (ii) misperceptions of other members' influence in joint family evaluations. We propose a two-stage conjoint approach to study these potential errors. Stage one compares family members' projections of each other's preferences to members' self-reported preferences. Stage two compares family members' projections of each other's influence to observed influence in joint family preferences. An empirical illustration shows that family members are relatively poor predictors of preference, but fairly accurate predictors of influence, in the area of family holiday preferences.     

Culture, economic development, and national ethical attitudes

To understand the influence of culture on ethical attitudes, a variety of countries must be compared simultaneously to avoid confounding of cultural dimensions. This study uses data from the World Values Survey to develop a measure of ethical attitudes that shows partial measurement invariance across 44 countries. Regressing the resulting latent means on four cultural dimensions [Hofstede G. Culture's Consequences: comparing values, behaviors, institutions, and organizations across nations. 2nd ed. Beverly Hills, CA: Sage Publications, 2001] and per capita gross domestic product (PCGDP) reveals effects that are not suggested by examining the predictors in isolation, and explains more variance than analysis of the raw means. However, the model does not account for ethical attitudes reported in Brazil, Japan, and the Philippines. In the remaining 41 countries, uncertainty avoidance, power distance, and PCGDP are found to have negative influences on national ethical attitudes.     

AIDS and economic growth: A human capital approach

Using a model that combines growth and health capital equations this study analyses the impact of HIV/AIDS on economic growth. The econometric results indicate that the epidemic's effects have been substantial; in Africa the marginal impact on income per capita of a 1% increase in HIV prevalence rate is minus 0.59%. Even in countries with lower HIV prevalence rates the marginal impacts are non-trivial. Hence while the human and social costs of the HIV/AIDS epidemic are major causes for concern, these results indicate that the macroeconomic affects of the HIV/AIDS epidemic are important.     

Correcting for On-Site Sampling in Random Utility Models

This study demonstrates how the joint distribution of a set of conditional trip counts to a system of recreation-sites can be adjusted for on-site sampling. An econometric approach is proposed that addresses both the size-biased distribution of the sampled visits and the weighted distribution of reported visits to ancillary destinations in a multivariate random utility framework. Estimation results indicate that uncorrected models produce biased estimates of trip counts and welfare measures. The empirical application examines jet skiing in the Lake Tahoe region.
