Consumption of foods and foodstuffs processed with hazardous chemicals: a case study of Bangladesh

Determining the best way to persuade consumers to consume more healthy foods is challenging. In Bangladesh, however, daily newspapers consistently show that various hazardous chemicals (e.g. calcium carbide, sodium cyclamate, cyanide and formalin, etc.) are mixed with or added to foods and foodstuffs. These chemicals are very dangerous to humans. This present study examines the reasons behind the use of hazardous chemicals in foods as well as the extent to which food producers/sellers use such chemicals. In addition, this study assesses consumer perceptions of and attitudes towards these contaminated food items and explores how adulterated foods and foodstuffs affect consumer health. The empirical data were collected from 110 consumers, 25 sellers or producers, seven doctors and seven pharmacists in Dhaka, the capital of Bangladesh. This study shows that nearly every consumer (93.7%) is aware that various foods and foodstuffs contain hazardous chemicals, and that 95.5% of consumers are aware that these adulterated foods and foodstuffs are harmful to their health. This paper explores the myriad reasons why consumers nevertheless feel compelled to consume such chemically treated foods.     

Lewis Growth Model and China's Industrialization*

This paper examines China's industrialization in the light of the Lewis growth model. It begins with a perusal of Lewis's own writings and those of Fei and Ranis to clarify certain assumptions and predictions of the Lewis model. The paper then reviews previous applications of the Lewis model in studying industrialization of other countries, and notes the methodological problems that arise in this regard. In applying the Lewis model to study China's industrialization, the paper focuses on the dynamic relationship between wage and marginal product of labor in the traditional sector. For this purpose, the paper estimates a production function for China's agricultural sector using province level data and compares the estimated marginal product of labor with the corresponding wage of the sector. The results show that the marginal product has been increasing (from below) at a faster pace than the wage, as is predicted by the Lewis model. The results indicate that China as a whole is steadily moving toward the Lewis Turning Point.     

The Weibull distribution as a general model for forecasting technological change

This paper presents a simple and widely applicable model for technological forecasting using the Weibull distribution function. It shows the generality of the Weibull function, which can accommodate different patterns of technological change. A method for estimating parameters and some applications are presented to illustrate the usefulness of the model.     

An exercise to evaluate an anti-poverty program with multiple outcomes using program evaluation

To measure the effectiveness of programs with multiple outcomes, I combine multidimensional poverty measures with difference-in-difference matching estimators. I apply this technique on an anti-poverty program and show it is a more comprehensive measure of poverty reduction than a unidimensional measure.     

AGRICULTURAL EXPORTS OF DEVELOPING COUNTRIES: ESTIMATES OF INCOME AND PRICE ELASTICITIES OF DEMAND AND SUPPLY

This paper provides new evidence on income and price elasticities of demand and supply of agricultural exports from developing countries, on the basis of (a) a consistent and fully specified supply and demand model, and (b) statistical estimation procedures not frequently used in the estimation of agricultural export functions. Estimates of price and income elasticities of demand for aggregate agricultural exports for all developing countries taken together — as distinct from individual exporting countries — are found to be low; moreover, export price as distinguished from non-price factors plays a relatively insignificant role in increasing export supply. Hence, an attempt by all developing countries to expand traditional agricultural exports with low price elasticity of demand may not yield rising earnings for all; but in fact may result in falling export revenues. Insofar as individual exports of all developing countries (not individual countries) are concerned, income and price elasticities of demand for such tropical commodities as tea, coffee, cocoa and bananas are also found to be low, except for new, non-traditional exports like pineapples. This indicates the importance of diversification of agricultural exports as a vehicle for their future growth.

Real exchange rates and job flows: evidence from Turkey

This study investigates the effects of the real exchange rate on job flows in Turkish manufacturing industries between 2006 and 2015 using data at the four-digit NACE Revision 2 level. Using dynamic panel data models, we find that a real appreciation increases gross and net job creation rates, and that the effect of appreciation is magnified as the exposure to international competitiveness of industries increases. We think that this is because Turkish manufacturing firms import a greater share of their inputs compared to the firms in developed countries. Hence, an appreciation creates more jobs because lower imported input costs enable firms to outcompete foreign producers.     

Can immigrants insure against shocks as well as the native-born?

We examine the impact of job displacement and serious health problems on multiple measures of individual and household well-being using longitudinal data. We extend the previous literature by examining whether these shocks have differential effects for the native-born and immigrants and whether shock mitigation strategies and their effectiveness differ by immigration status. Our results suggest that both immigrants and native-born individuals have access to similar institutional and other formal and informal risk-sharing arrangements such that they are able to mitigate shocks against job loss or illness almost equally.     

Fishermen’s competitiveness and labour market performance: Evidence from shrimpers in Bangladesh

We conduct an experiment to determine competitiveness among shrimpers who engage in collecting shrimp seeds in the southwestern coastal region of Bangladesh. We then examine how competitiveness affects the labour supply decisions and labour market performance of these shrimpers. Our results show that shrimpers who prefer competition are more productive than shrimpers who do not prefer competition. Competitive shrimpers secure better prices and earn higher incomes selling their catches. We estimate that their wage elasticity of participation ranges from 0.4 to 0.5, which is consistent with preferences under neoclassical assumptions. Competitive shrimpers have a slightly greater wage elasticity than non-competitive shrimpers, suggesting that they might be more responsive to expected earnings. Our results have important policy implications for the efficient management of common pool resources.     

Strategic default,multiple installments,and the role of informal moneylender in microcredit contract

I model the role of strategic defaults and informal moneylenders on multiple-installment loan contracts offered by microfinance institutions (MFIs). The results show that a single-installment loan is not viable due to MFIs' vulnerability to strategic defaults and borrowers' lack of collateral. In contrast, a multiple-installment contract requires borrowers to borrow from the moneylender, who is immune to strategic default, in order to repay the MFI's early installments that are due before the project yields a return. Consequently, both default costs and borrowing costs increase and incentives to commit strategic default decline, making the multiple-installment contract profitable for MFIs.
