Market Segmentation Research: Beyond Within and Across Group Differences

Market segmentation research is currently focused too narrowly on the task of segment identification as opposed to its strategic relevance within a firm. In this paper we distinguish an ex ante approach to market segmentation research, which begins with studying the motivating conditions that lead people to the tasks and interests in their lives, from an ex post approach which begins with an individual's reaction to marketplace offerings. We argue that the marketing task of guiding managements to make what people will want to buy will be more successful in light of a deep understanding of behavior in the context of everyday life and work, rather than a detailed understanding of preferences in the marketplace. Directions for future research are discussed.     

Trade Policy Transparency and Investor Confidence: Some Implications for an Effective Trade Policy Review Mechanism

This paper is concerned with the value of the WTO's Trade Policy Review Mechanism, particularly its transparency role and its potential role in policy stability, for investor confidence in developing countries. The implications of reduced risk and uncertainty regarding trade policy for investor confidence, and ultimately for the capital stock and the long-run structure of production, are examined in an analytical model. Certainty equivalence is employed to assess the general equilibrium effects of risk and uncertainty. Their reduction can boost risk-adjusted returns, leading to an increase in long-run levels of capital.     

Market Structure and Market Access

We explore an issue at the nexus of domestic competition policy and international trade, the interaction between goods trade and market power in domestic trade and distribution sectors. We examine the effect of variations in conditions of domestic competition in services on trade volumes in goods in the cases of both linear and nonlinear import demand, including standard form CES‐based gravity models of bilateral trade flows. Theory suggests a set of linkages between service‐sector pricing and goods trade supported by econometrics involving imports of 22 OECD countries vis‐a‐vis 69 exporters. Competition in distribution services affects the volume of trade in goods. Additionally, because of interaction between tariffs and pricing, the market structure of the domestic service sector becomes increasingly important as tariffs are reduced. Indeed, depending on the degree of competition, market access concessions on tariffs may be effectively undone in some cases by changes in margins. For exporters, we find that service competition in destination markets matters most for exporters from smaller, poorer countries. Our results also suggest that while negotiated agreements leading to cross‐border services liberalisation may boost goods trade as well, they may also lead to a fall in goods trade when such liberalisation involves FDI leading to increased service sector concentration.     

Optimal Poverty Reduction, Adjustment, and Growth

This article analyzes poverty reduction policies in an appliedoptimal growth framework. Assuming that poverty reduction iseffected through redistribution, it focuses on the static anddynamic tradeoffs between equity and efficiency and on the choicebetween current income and future income (that is, current productiveasset) transfers to the poor. By numerically estimating a stylizedeconomy, it is shown that, given reasonable assumptions aboutbehavioral parameters, the efficiency cost of poverty reductionin an economy on a steady growth path is relatively low. Ina period of adjustment following a severe exogenous shock, however,the scope for redistribution may be extremely limited if thereis a constraint on foreign borrowing. Plausible examples aregiven of adjustment cases in which poverty reduction becomesoptimal only after partial adjustment has been achieved.     

Alternative interpretations of hours information in an econometric model of labour supply

This paper examines the labour supply behaviour of married women in France. A sequence of models is specified and estimated which incorporate different amounts of information on observed weekly hours. In all models the distinction is drawn between search and non-participation among non-workers. We provide extensive specification diagnostics, including Heckman-Andrews tests, as well as Hausman tests for the comparison of different handlings of the hours information. It turns out that distinguishing between part-time, full-time and long hours gives virtually the same results as treating observed hours as reflecting desired hours.     

Schumpeterian cycles with pro-cyclical R&D

Recent empirical work finds that R&D expenditures are quite pro-cyclical even for firms that are not credit-constrained during downturns. This has been taken as strong evidence against Schumpeterian-style theories of business cycles that emphasize the idea that downturns in production may be good times to allocate labor towards innovative activities. Here we argue that the pro-cyclicality of R&D investment is in fact quite consistent with at least one of these theories. In our analysis we emphasize three key features of R&D investment relative to other types of innovative activity: (1) it uses knowledge intensively, (2) it is a long-term investment with uncertain applications, and (3) it suffers from diminishing returns over time.
