Efficient choice set designs for estimating availability cross-effects models

Batsell and Polking proposed a discrete choice model which incorporates the availability (presence or absence) of competing brands into the utility of each brand under study. The information on relative impacts of adding or deleting brands is of strategic interest, and models that do not incorporate such effects may be misleading. The designs suggested by Batsell and Polking have 2^m–m–1 choice sets. Even with as few as 10=m brands, this requires over 1000 choice sets. In this paper we provide a catalog of designs for estimating cross effects models in as few as 2m–1 choice sets. This will make cross effects modelling practical in a wide range of academic and commercial settings.     

Foreign trade potential,small enterprise development and job creation in developing countries

Increasing American competitiveness in the international economy requires expanding trade with emerging markets, especially in developing countries of Asia, Latin America and Africa. Historically, as developing countries' economies have grown, the capacity for exporting and importing have both expanded. In the future, the capacity for trade in developing countries will depend increasingly on their ability to create sufficient numbers of jobs to absorb their rapidly growing labor forces.Unlike Western countries, most developing economies have a small percentage of their labor forces in large-scale manufacturing and a large share engaged in small-scale and informal sector enterprises. Small-scale enterprises have been the primary sources of labor absorption in cities in developing countries and will continue to play a crucial role in the future. Experience has shown that policies for improving the capacity of small-scale enterprises to generate jobs have had only mixed results in developing countries. The challenge facing governments and the private sector in the future include: (1) creating an economic environment conducive to small-enterprise development; (2) removing regulatory and administrative obstacles to small-enterprise expansion; (3) tailoring small-enterprise promotion programs to local conditions and needs; (4) providing capital and credit for small-business owners; (5) involving the private sector in small-enterprise development programs; and (6) providing technical assistance, training and educational programs through public-private partnerships.     

Innovation,firm size,and firm age

This paper uses a new data set on innovation output to assess the degree to which the level of innovation in manufacturing firms is influenced by firm size and firm age. Indicators of innovation output used are the number of new products introduced as a function of firm sales and the proportion of firm sales obtained from products first introduced in the previous five years. While the evidence is mixed, the results tend to indicate that it is possible to separate the effects of age and size in assessing the level of innovation. Both firm size and firm age tend to be inversely related to innovative output.     

Price and profitability in fish smoking in southwestern Nigeria

Comparative market prices for four freshwater and four marine fish species in the raw and processed forms were determined in a survey within Lagos and Oyo States of Nigeria. Costs of processed fish were calculated relative to the sale prices of their raw equivalents, taking moisture differences and cost of processing into consideration. All the species would have to be sold in the processed form for much higher prices than was found during the survey if sales were to be by weight. Processed catfish, sardine, mudfish and mackerel appear to be sold at a loss while three species (tilapia, sole and bongafish) are sold at very marginal profit. Only tigerfish is sold at reasonable profit. It is suggested that anyone going into fish smoking as a modern business venture should be prepared to face unfair competition in pricing from the small operators who appear to be underpricing their products and who currently dominate almost the entire fish market in Nigeria.     

Satisfaction with household production: the effect of time spent in household production by husbands and wives

The purpose of the study was to examine the relationship between the extent of household production and satisfaction with household production. Data were obtained from 400 married couples who responded to a postal questionnaire. The dependent variable was an index of satisfaction incorporating two aspects of household production, quality and quantity. Regression analysis indicated that of the three variables representing the extent of household production in the model — hours spent by each spouse in household production and an activity index to measure the number of household production activities — only husband's hours spent in household production demonstrated a significant, independent effect. Other significant variables included husband's hours of market work, household net worth, age of respondent and gender of respondent. Two significant interactions indicated that (i) the relationship between wife's hours of household production and satisfaction with household production differed according to the gender of the respondent, and (ii) the relationship of husband's hours of market work and satisfaction differed according to the age of the respondent.     

The global markets of renewable energy sources and the national interests of Russia

The current state and the prospects of the use of renewable energy sources (RES) in the world, their total and technical potential and fields of application, and their advantages and disadvantages in comparison with fossil kinds of fuel are considered. Special attention is given to nonconventional RES. The reasons why Russia is lagging behind in the use of these sources are analyzed.

Price Stability and the Case for Flexible Exchange Rates

We revisit Friedman’s case for flexible exchange rates in a small open economy with several distortions and rigidities and a variety of domestic and external shocks. We find that, for external shocks, the flexible exchange rate regime outperforms the fixed regime independent of the source of domestic nominal rigidities provided that the monetary authorities pursue a policy of strict inflation targeting. For domestic supply shocks, a joint policy of a flexible exchange rate and strict inflation targeting fares well when the main source of nominal rigidities is in the domestic goods markets, but not if rigidities arise in the labor markets.
