CONSUMPTION GROWTH ACCOUNTING

The methodology in this paper combines an input–output structural decomposition approach with the supply-side perspective of mainstream growth accounting. In explaining the intertemporal change in consumption per worker, three sets of effects are distinguished. First, contributions due to several types of technological changes are considered. Second, effects caused by changes in international trade are discerned. Third, composition effects that reflect structural shifts in demand (including changes in tastes) are quantified. As an empirical illustration, we analyze the developments in the U.K. between 1979 and 1990.     

Sectoral Energy- and Labour-Productivity Convergence

This paper empirically investigates the development of cross-country differences in energy- and labour productivity. The analysis is performed at a detailed sectoral level for 14 OECD countries, covering the period 1970–1997. A σ-convergence analysis reveals that the development over time of the cross-country variation in productivity performance differs across sectors as well as across different levels of aggregation. Both patterns of convergence as well as divergence are found. Cross-country variation of productivity levels is typically larger for energy than for labour. A β-convergence analysis provides support for the hypothesis that in most sectors lagging countries tend to catch up with technological leaders, in particular in terms of energy productivity. Moreover, the results show that convergence is conditional, meaning that productivity levels converge to country-specific steady states. Energy prices and wages are shown to positively affect energy- and labour-productivity growth, respectively. We also find evidence for the importance of economies of scale, whereas the investment share, openness and specialization play only a modest role in explaining cross-country variation in energy- and labour-productivity growth.      

WHICH AGGLOMERATION EXTERNALITIES MATTER MOST AND WHY?

This paper revisits the ongoing discussion on the importance of agglomeration externalities – specifically specialization, diversity and competition effects – that may contribute to innovation, productivity and urban employment growth. Previous meta‐analyses suggested that the evidence on agglomeration externalities is strongly context‐specific. Expanding an earlier analysis of 31 articles, we seek to draw in this paper more robust conclusions by means of the statistical evidence for agglomeration externalities presented in 73 scientific articles, all building on the seminal work of Glaeser et al. (1992). Our results confirm that the heterogeneity among studies is huge and can only be partially accounted for by means of an ordered probit analysis. Additionally, some evidence of publication bias is found. We conclude that the conventional lines of inquiry in this literature may now have reached strongly diminishing returns. New lines of inquiry, using rich micro‐level data on firms and workers, dynamic general equilibrium models at the macro level, more attention for spatial and temporal variation in the impacts of agglomeration, and further investigations into the spatial scope of externalities are promising avenues for further research that can enhance our understanding of how agglomeration externalities continue to fuel our increasingly urbanized world.     

An integrated approach for ex-ante evaluation of public policies for sustainable agriculture at landscape level

An integrated methodological framework for ex-ante evaluation and planning of public policies for sustainable agriculture at agro-landscape level is proposed. The components of the framework are to: (1) determine the private, i.e. farmers’, and public benefits associated to agro-landscapes, consisting of an agricultural land-use system, according to its performance for several market and non-market functions. Market forces determine the market benefits and preferences of society the non-market benefits; (2) explore and select potential sustainable agro-landscapes based on the private and public benefits associated with possible land-use alternatives; (3) define efficient public policy mechanisms for improving social net benefit of agro-landscapes.The framework is illustrated with a case study in a small dairy farming dominated agro-landscape in The Netherlands, with gross margin, landscape quality, nature value and environmental health as the analysed ecosystem functions. Alternative landscapes consisting of hedgerow configurations and grassland management practices were explored, yielding a set of alternatives representing the solution space in terms of change in private and public benefits. Policy mechanisms were defined to move from the current to a desired landscape based on changes in social net benefits. Moreover, the necessity of a modification in the current agri-environmental support was analysed for each landscape. The analysis considered all farmers in the agro-landscape jointly. The results for the case study showed potential prototypes of landscapes and their performance compared to the current landscape. Extension was the most efficient policy mechanism to promote the change to the socially optimum landscape alternative.     

The Labor-Managed Firm: Permanent or Start-Up Subsidies?

We explore a new argument that seeks to explain the near absence of the labor-managed firm or cooperative, despite a range of inefficiencies attributed to the present-day capitalist firm. We derive the crucial condition for the emergence of labor-managed firms and show that it is unduly restrictive from an efficiency point of view. The policy implication is that public intervention to promote labor-managed firms should primarily be in the form of start-up subsidies rather than in providing permanent tax subsidies.     

Common socio-economic cycle periods

We present a meta-analysis of cycle periods in historical socio-economic data found in the K-wave literature. The literature on stochastic and deterministic cycles in variables such as the consumer price index, employment, interest rates, commodity prices, GDP, war and hegemony is huge and scattered. However our meta-analysis reveals various commonalities. Our key finding is that there is a common set of cycle periods that is common across most socio-economic variables.     

Trust and economic growth: a robustness analysis

This paper analyses the robustness of results on the relationshipbetween growth and trust previously derived by Knack and Keefer(1997) and Zak and Knack (2001) along several dimensions, acknowledgingthe complexity of the concept of robustness. Our results showthat the Knack and Keefer results are only limitedly robust,whereas the results found by Zak and Knack are highly robustin terms of significance of the estimated coefficients and reasonablyrobust in terms of the estimated effect size. The improvementin robustness is caused by the inclusion of countries with relativelylow scores on trust (most notably, the Philippines and Peru).Overall, our results point at a relatively important role fortrust. However, the answer to the question how large this payoffactually is depends on the set of conditioning variables controlledfor in the regression analysis and—to an even larger extent—onthe underlying sample.     

Tax Level and Tax Internalization Effects on Union Wage Bargaining

High taxes and generous social benefits are often blamed for causing unemployment. The conventional view is that if taxes on labour are (too) high, jobs will be lost and that generous social benefits will exert an upward pressure on unions' wage claims. In the case where unions co-ordinate their wage bargaining strategy, this need not be the case. A simple model is used to illustrate the effects of the tax rate level and tax internalization on unions' wage bargaining strategy. A high marginal tax rate along with endogeneity of the average tax rate shifts the union's trade-off between wages and employment in favour of the latter. These shifts may have contributed to the success of the so-called polder model or tulip model of the Netherlands.     

Macroeconomic Consequences of Outsourcing: An Analysis of Growth, Welfare, and Product Variety

Outsourcing of non-core activities is nowadays a common business strategy. Declining transaction and transportation costs caused by the advent of Information and Communication Technology are a potentially important driving force behind this development. This paper provides a theoretical framework for analysing a firm's incentive to follow such a strategy of outsourcing and its consequences for macroeconomic variables like growth and product variety. We divide production activities into core and non-core activities. Non-core activities can be performed within the firm or can be mediated by the market. We derive conditions under which outsourcing occurs, and under which outsourcing is socially desirable. These conditions do not necessarily coincide. Outsourcing may hence be a profitable strategy for firms, while it is socially suboptimal. Crucial parameters in the model are the relative scale of core versus non-core activities, management costs, transaction costs and love for variety of consumers.
