Intertemporal price discrimination and consumer demand

Under a particular class of utility functions, intertemporal price discrimination (IPD) is not feasible. That is, customers cannot be made to pay different prices for a durable good at different points in time. Other factors such as falling costs, and differing discount rates between buyers and sellers have been found to make intertemporal pricing schemes feasible, or even profitable. None of these factors, however, were fundamental demand differences which give rise to static price discriminations. In this paper we argue that IPD is indeed feasible and sometimes profitable, if only we allow for a nondurable good in the utility function. A simple additively separable utility is examined first, which is then extended to a nonseparable utility function which allows richer substitution/complementary relations between the durable and the nondurable goods. This may help us to better understand the similarities between static and intertemporal price discriminations.     

Intertemporal preference parameters for some European monetary union countries

In the European Monetary Union, the estimation and analysis of preference parameters in its members is of special interest because possible differences could help us to understand why a common monetary policy could have different effects on the different economies involved. In this article, we have focused our attention on the elasticity of intertemporal substitution, one of the key preference parameters in intertemporal macroeconomic models. Several studies have shown a possible underestimation of such elasticity for different countries. It is common practice to estimate the parameter using only nondurable goods and services consumption data, without referring to the flow of services generated by durable consumption. This is only admissible if the intratemporal utility can be separated among the different consumption components. Our first objective is, therefore, to test the assumption of intratemporal separability for a selection of European countries (Germany, Spain and France), and then to analyse the effect of durable consumption on the estimated values of the intertemporal elasticity of substitution of these countries, our ultimate goal. Knowledge of such elasticity will enable us to characterise how saving in these economies reacts to variations in the real interest rate.     

Industrial policy in developing countries

Traditionally, proindustry policies were associated with incentives for import substitution and an inward-oriented development strategy. This is no longer so. Whereas in the past, world-market orientation was seen as implying reliance on primary production, today policies favoring international competition and export orientation are considered compatible with policies favoring rapid industrialization. Differences of opinion on the appropriate degree of public intervention remain. The debate between “purist” laissez-faire advocates and those who believe in industrial planning, public investment, and generous subsidies often obscures the real need for reduction in antiexport bias, rationalization of incentives, and reform of public-sector activities.     

Taxation base in developing countries

Informal sectors are larger in developing countries than in rich countries. This is a result of higher fixed costs of entry into the formal economy in developing countries. We show that raising barriers to entry is consistent with a deliberate government policy for raising tax revenue. By generating market power, and hence rents, for the permitted entrants, market entry fees foster the emergence of large taxpayers. The rents can be readily confiscated by the government through entry fees and taxes on profits at a low administrative cost. The relevance of the theory is assessed with a sample of 64 countries. Empirical analysis supports the results of the paper.     

International trade between consumer and conservationist countries

We consider trade between a ‘consumer’ country with an open access renewable resource and a ‘conservationist’ country that regulates resource harvesting to maximize domestic steady-state utility. In what we call the mild overuse case, the consumer country exports the resource good and suffers steady-state losses from trade, as suggested by the conventional wisdom that weak resource management standards confer a competitive advantage on domestic firms in the resource sector but cause welfare losses. Strikingly, however, when the resource stock is most in jeopardy, the conservationist country exports the resource good in steady state and both countries experience gains from trade.     

Age-differentiated minimum wages in developing countries

The fact that minimum wages seem especially binding for young workers has led some countries to adopt age-differentiated minimum wages. We develop a dynamic competitive two-sector labor market model where workers with heterogeneous initial skills gain productivity through experience. We compare two equally binding schemes of single and age-differentiated minimum wages, and find that although differentiated minimum wages result in a more equal distribution of income, such a scheme creates a more unequal distribution of wealth by forcing less skilled workers to remain longer in the uncovered sector. We also show that relaxing minimum wage solely for young workers reduces youth unemployment but harms the less skilled ones.

Manufacturing growth accelerations in developing countries

This paper investigates the factors driving manufacturing growth accelerations in a sample of 134 developing countries over the period 1970 to 2014. We first identify growth acceleration episodes of manufacturing value added (MVA) by their year of initiation and according to a country’s income classification. We then estimate a probit model to explain what factors predict these MVA growth accelerations. Our results show that human capital and institutions represent contextual factors that favor the growth of manufacturing, together with macroeconomic policies related to investment, and openness to foreign trade and capital. We also find that most of these factors not only foster episodic accelerations of industry, but they contribute as well to a sustained process of industrialization that characterized the process of economic growth of a few successful countries over the period 1970 to 2014.     

Growth and poverty in developing countries

Despite the developing countries' impressive aggregate growth of the past 25 years, its benefits have only reached the poor to a very limited degree. Not only have the poorest countries grown relatively slowly, but growth processes are such that within most developing countries, the incomes of the poor increase much less than the average. Although many policies have been proposed to counter these trends, little has been done to estimate the possibilities for significantly reducing world poverty within a reasonable period. This paper develops a quantitative framework to project levels of poverty under different assumptions about GNP growth population growth and changes in income distribution. Although the interactions among development processes and policy instruments are not modelled in any detail, the results serve to clarify the nature of the problem. The policy simulations demonstrate that the elimination of absolute poverty by the end of this century is a highly unlikely prospect; even to achieve a substantial reduction will require a combination of policies designed to accelerate the growth of poor countries, to distribute the benefits of growth more equitably, and to reduce population increase.     

Geographical dispersion of consumer search behaviour

This article investigates whether consumer search behaviour differs across zip codes within the U.S. As an application, daily gasoline price data covering virtually all gas stations within the U.S. are employed to estimate the distribution of search costs in each zip code. The results show that there are significant differences across zip codes regarding the expected number of searches achieved before consumers purchase gasoline. In order to have a systematic explanation, such differences are further connected to geographic, demographic, and economic conditions of the zip codes in a secondary analysis. The corresponding results imply several strategies for gas stations in order to maximize profits/markups; suggestions follow for policy makers and regulators to reduce redistributive effects of information barriers across locations.     

Intertemporal substitution and random changes in preferences: Time series evidence for four countries

This study attempts to estimate a model of intertemporal substitution taking into account serially correlated changes in preferences with quarterly aggregate time series data for the USA, Great Britain, West Germany and Switzerland. Thereby, necessary optimality conditions representing the trade-offs between present and future consumption, present and future leisure, as well as present consumption and leisure are estimated using the forward-filtered estimator of Hayashi and Sims. The estimation results obtained for the dynamic optimality conditions reject the model formulated. The analysis of the static optimality conditions gave more satisfactory results with respect to intertemporal substitution elasticity in consumption.     

Technology assessment and developing countries

The assessment of technologies may be of great importance to developing countries in their present process of industrialization in the framework of the New International Economic Order. The main criteria for the assessment of the technologies most relevant to the needs of developing countries are reviewed from the point of view of employment, scarce capital, and energy resources. The design of appropriate technologies should take into account the tastes, culture, needs, purchasing power, and raw materials available in developing countries. A systems approach should therefore be used to assess technologies. The programs undertaken by several agencies of the United Nations System are described which may contribute to build up technology assessment capability in developing countries.     

Decentralizing antipoverty program delivery in developing countries

We study the effects on accountability in government service delivery of decentralizing administration of an antipoverty program. While governments at both central and local levels are vulnerable to antipoor policy biases owing to political capture, centralized delivery systems are additionally prone to bureaucratic corruption, owing to problems in monitoring bureaucratic performance. Decentralizing the delivery system promotes cost-effectiveness and improves intraregional targeting at low program scales. But interregional targeting may deteriorate, as central grants to high-poverty regions shrink, owing to high capture of local governments by local elites in such regions.     

Recent trends in trade among developing countries

The paper presents the early results of empirical work on trade among developing countries. The main conclusion is that non-fuel trade among developing countries, excluding capital surplus oil exporters, remained a remarkably stable share of their total trade between 1963 and 1977. This constancy does, however, conceal two interesting opposing trends: The share of manufactures exported to developing countries has been falling sharply, while that of non-fuel primary commodities has been rising, the latter largely because of the demands of the newly industrializing countries. Nevertheless, the dynamism of manufactures has meant that they make up an increasing share of trade among developing countries. Four particular points emerge from the evidence: (i) there is no obvious sign of a bias against trade among developing countries, except whatever effect their own commercial policies may have; (ii) the more inward-looking countries tend to send a higher proportion of their exports to other developing countries and regional integration strengthens this effect; (iii) exports of manufactures to developing countries are much more capital intensive than those to industrialized countries; and (iv) exports to developing country markets may not be the vital first stage for capital goods exports that is sometimes supposed.     

Determinants of offshore production in developing countries

The factors that discourage or block ordinary exports and thus promote the use of offshore production as an alternative for developing countries are examined. They prove to be barriers to entry related both to production and marketing, in contrast to those for developed countries, which are limited to marketing-related barriers to entry.     

Fiscal deficits and growth in developing countries

This paper examines the relation between fiscal deficits and growth for a panel of 45 developing countries. Based on a consistent treatment of the government budget constraint, it finds evidence of a threshold effect at a level of the deficit around 1.5% of GDP. While there appears to be a growth payoff to reducing deficits to this level, this effect disappears or reverses itself for further fiscal contraction. The magnitude of this payoff, but not its general character, necessarily depends on how changes in the deficit are financed (through changes in borrowing or seigniorage) and on how the change in the deficit is accommodated elsewhere in the budget. We also find evidence of interaction effects between deficits and debt stocks, with high debt stocks exacerbating the adverse consequences of high deficits.     

Intertemporal sustainability of current account imbalances: New evidence from the OECD countries

This study estimates the intertemporal model for the relationship between exports and imports and examines the sustainability of current account deficits (CADs) and the validity of intertemporal budget constraint for 24 Organisation for Economic Co‐operation and Development countries. The standard ordinary least squares (OLS)‐based two‐step Engle and Granger test, the cointegration regression Durbin–Watson (CRDW) test, and the Stock–Watson test performed on the one‐regime model with time‐invariant parameters and no structural break provide mixed support for the presence of cointegration between exports and imports. The recursive least squares‐based cumulative sum of recursive residuals (CUSUM) and the cumulative sum of squares of recursive residuals (CUSUMSQ) tests and the OLS‐based Andrews‐Quandt (AQ) and Andrews – Ploberger (AP) tests suggest the presence of structural breaks in the long‐run relationship between exports and imports for a number of countries. The end‐of‐sample new cointegration breakdown tests performed on the OLS, fully modified OLS, and full‐information maximum‐likelihood estimates of the model suggest the presence of cointegration between exports and imports for most countries. The dominant support for cointegration between trade flows points toward the sustainability of CADs and the validity of intertemporal budget constraint. The macroeconomic stabilization policies seem to have been effective in correcting the market failures and maintaining the steady‐state equilibrium relationship between trade flows in the sample countries. The findings of this study have important implications for empirical research. The structural breaks in the cointegrating vector could occur even over the short time periods and at any point in time. It is essentially important to assess the sustainability of the external position in the presence of long‐period as well as short‐period breaks in the cointegrating vector.     

Elections and economic policy in developing countries

This paper explores the impact of elections on economic policies and governance in developing countries. We distinguish between a structural effect, which increases accountability, and a cyclical effect which may be disruptive. Since the effects are offsetting, neither can be analysed in isolation. We implement an econometric analysis on more than 80 developing countries using positive changes in the Country Policy and Institutional Assessment of the World Bank and the International Country Risk Guide as signalling improvements in economic policy and governance. We find that both structural and cyclical effects matter. The cyclical effect suggests that mid-term is the best moment for policy change. We investigate the structural effect by comparing different frequencies of elections. Except at the extremes, a higher frequency of elections improves both policy and governance net of any cyclical effect. The important exception to this benign net effect is if the electoral process is badly conducted. Badly conducted elections have no structural efficacy for policy improvement. A reasonable interpretation of our results is that honest elections increase accountability and thereby discipline governments to improve economic policy and governance, but that if candidates can win by fraud this chain is broken.
