Cross-sectional facts for macroeconomists

This article provides an introduction to the special issue of the Review of Economic Dynamics on “Cross-Sectional Facts for Macroeconomists”. The issue documents, for nine countries, the level and the evolution, over time and over the life cycle, of several dimensions of economic inequality, including wages, labor earnings, income, consumption, and wealth. After describing the motivation and the common methodology underlying this empirical project, we discuss selected results, with an emphasis on cross-country comparisons. Most, but not all, countries experienced substantial increases in wages and earnings inequality, over the last three decades. While the trend in the skill premium differed widely across countries, the experience premium rose and the gender premium fell virtually everywhere. At a higher frequency, earnings inequality appears to be strongly counter-cyclical. In all countries, government redistribution through taxes and transfers reduced the level, the trend and the cyclical fluctuations in income inequality. The rise in income inequality was stronger at the bottom of the distribution. Consumption inequality increased less than disposable income inequality, and tracked the latter much more closely at the top than at the bottom of the distribution. Measuring the age-profile of inequality is challenging because of the interplay of time and cohort effects.     

Integration of third parties within existing dyads: An exploratory study of category management programs (CMPs)

In this study, we focus on the pursuit of cross-functional integration between suppliers and retailers along the different phases of a collaborative project. More specifically, we explore why and how, a supplier and retailer would want to shift the locus of integration from the dyadic to the network level by adding a third party to an ongoing relationship.A case study is developed to analyze the process of integration in the context of category management programs. The analysis reports on a program developed by a regional retailing chain based in the south of Italy, with the collaboration of a national coffee blends supplier and a third-party leader in the market analysis service business.The findings offer a novel view of third parties' role, which broadens the scope from a typical, initial support of negotiations to an evolving modality of intervention during the different phases of the collaborative project. More precisely, the third party enables the sequential and joint activation of alternative forms of interaction between the parties, which is pivotal for enacting the integration mechanism that is most suitable for each program phase.These findings offer a rich set of insights for the analysis of integration within distribution channel and supply chains, as well as for category management and, more generally, for knowledge management in marketing relationships.     

Some consequences of the unknottedness of the Walras correspondence

Two basic properties concerning the dynamic behavior of competitive equilibria of exchange economies with complete markets are derived essentially from the fact that the Walras correspondence has no knots.     

Weathering the Storm: The Impact of the East Asian Crisis on Farm Households in Indonesia and Thailand

This article assesses the impact of the East Asian financialcrisis on farm households in two of the region's most affectedcountries. Indonesia and Thailand, using detailed household-levelsurvey data collected before and after the crisis began. Althoughthe nature of the shocks in the two countries were similar,the impact on farmers' income (particularly on distribution)was quite different. In Thailand, poor farmers bore the bruntof the crisis, in part because of their greater reliance onthe urban economy, than did poor farmers in Indonesia. Urban-rurallinks are much weaker in Indonesia. Farmers in both countries,particularly those specializing in export crops, benefited fromthe currency devaluation. Although there is some evidence thatthe productivity of the smallest landholders declined over theperiod in question, it is difficult to attribute this directlyto the financial crisis. At least in Thailand, a rural creditcrunch does not seem to have materialized.      

Opting Out,Collective Contracts and Labour Flexibility: Firm-Level Evidence for The Italian Case

This article analyses the role of deviations from higher level collective agreements adopted in firm-level bargaining to regain higher labour mobility, net positive employment effects and a resurgence of labour productivity. Using Italian firm-level data, after performing preliminary pooled ordinary least squares and fixed effects estimates, we adopt a difference-in-difference approach combined with a propensity score matching. All the estimations show that opting out clauses notably increases both hiring and separations, but without significant variations in terms of net employment. In addition, no significant labour productivity gains are obtained. The only significant change concerns the increase in the share of temporary workers.     

Stay in or get out the Janus? The maintenance of multiplex relationships between buyers and sellers

Buyers and sellers interact in different ways. They conduct economic transactions but often also engage in social exchanges; they compete to appropriate the value generated throughout the pipeline but often also collaborate in mutual value creation. Increasingly, they show patterns of repeated interaction rather than engaging in single transactions.Most past research investigated interaction modalities within buyer-seller relationships through an ‘or-or’ lens, and considered one modality as prevailing within the relationship at a given moment.In this study, we will develop an ‘and-and’ logic, opening the mainstream view of relationship maintenance to social theories on the structure of economic action and the strategy view of coopetition. We will further examine the implications of dualities and complementarities within buyer-seller relationships in respect of their maintenance over time.     

Why do parents socialize their children to behave pro-socially? An information-based theory

We present a model of intergenerational transmission of pro-social values in which parents have information about relevant characteristics of society that is not directly available to their children. Differently from existing models of cultural transmission of values (such as Bisin and Verdier, 2001, Tabellini, 2008) we assume that parents are exclusively concerned with their children's material welfare. If parents coordinate their educational choices, a child would look at her system of values to predict the values of her contemporaries, with whom she may interact. A parent may thus choose to instill pro-social values into his child in order to signal to her that others can generally be trusted. This implies that parents may optimally decide to endow their children with values that stand in contrast with maximization of material welfare, even if their children's material welfare is all they care about.     

The role of fiscal policy in Japan: a quantitative study

This paper analyzes the role of fiscal policy in the recent slowdown in Japan. A dynamic general equilibrium model is developed in which fiscal policy can have both expansionary effects (through increasing returns) and contractionary effects (through the increase of public debt and tax burden). A version of the model is calibrated to the Japanese economy and is used to measure the importance of both these effects. We find that, under a wide range of parameters, net expansionary effects are quantitatively small, thus suggesting a limited role for fiscal stabilization
