Zero‐Rating versus Cash Transfers under the VAT

To reduce the tax burden on the poor, nearly every VAT system allows for special treatment of certain goods or services. Zero‐rating the supply of certain foodstuffs is a prominent example of this practice. Using data on South Africa, this paper considers whether taxing foodstuffs alongside compensating cash transfers may be preferred to zero‐rating foodstuffs in a developing country context. The results show that cash transfers may be preferred if all the additional revenue from eliminating the zero rate can be earmarked and government is perfectly efficient. In the likely absence of earmarking and perfect efficiency, developing countries may need to apply special treatment to some foodstuffs to protect the poor. If this is the case, it is proposed that zero‐rating can be preferred to the exemption of certain foodstuffs.     

Liquidity-saving mechanisms in collateral-based RTGS payment systems

This paper studies banks’ incentives regarding the timing of payment submissions in a collateral-based RTGS payment system and how these incentives change with the introduction of a liquidity-saving mechanism (LSM). We show that an LSM allows banks to economise on collateral while also providing incentives to submit payments earlier. This is because in our model an LSM allows payments to be matched and offset in real time without any or very minimal funds. Under a collateral-based RTGS payment system, introduction of the LSM always improves welfare. The result contrasts with earlier work, which shows that under a fee-based RTGS system, the introduction of an LSM in some circumstances may reduce welfare.     

New economic geography meets Comecon

We analyse the internal spatial wage and employment structures of the Czech Republic, Hungary, Poland, Slovakia and Slovenia, using regional data for 1996–2000. A new economic geography model predicts wage gradients and specialization patterns that are smoothly related to the regions’ relative market access. As an alternative, we formulate a ‘Comecon hypothesis’, according to which wages and sectoral location are not systematically related to market access except for discrete concentrations in capital regions. Estimations support both the NEG (new economic geography) prediction and the Comecon hypothesis. However, when we compare internal wage and employment gradients of the five new member states with those of Western European countries, we find that the former are marked by significantly stronger discrete concentrations of wages and service employment in their capital regions, confirming the ongoing relevance of the Comecon hypothesis.     

The Throwaway Society: a Look in the Back Mirror

Whilst public criticisms of an increasingly wasteful consumer society emerged already in late nineteenth Century, the specific concept of a “Throwaway Society” was first used in the early 1960s. This short communication sketches the passionate debate around planned obsolescence and oversaturated consumers and offers a short historical glimpse at a persistent, existential problem that still awaits effective solutions.

Factors Determining the Adoption of Energy-Saving Technologies in Swiss Firms: An Analysis Based on Micro Data

This study investigates the factors that determine firms’ decisions to adopt energysaving technologies. We distinguish between the decisions of whether or not to use a technology (“inter-firm diffusion”), and of how intensely to use a technology (“intra-firm diffusion”). The empirical model used accommodates several effects that have been postulated in the theoretical diffusion literature: firm and industry heterogeneity, strategic considerations and external effects. Data for 2,324 Swiss firms for the year 2008 is used, with separate information for four categories of energy-saving technology applications (electromechanical and electronic, motor vehicles and traffic engineering, construction, power-generating processes). The results reveal significant differences with respect to firm characteristics and adoption barriers between inter-firm and intrafirm diffusion. In practically all cases, positive net external effects of adoption can be found. Inducement effects, particularly those traced back to intrinsic motivations for environment-friendly technologies, show clearly positive effects on adoption behavior.     

Economics at the FCC, 2011–2012: Spectrum Incentive Auctions, Universal Service and Intercarrier Compensation Reform, and Mergers

The past year in economics at the Federal Communications Commission covered a broad range of topics in telecommunications policy. This paper highlights the economic issues that are addressed in the following key areas: spectrum management, universal service and intercarrier compensation reform, and merger review. In spectrum management, the FCC received congressional authority to implement an ??incentive auction?? to repurpose television broadcasting spectrum into flexible-use licenses that will be suitable for mobile wireless service providers. We discuss some important issues in designing the auction. We next address some aspects of the FCC??s comprehensive reforms of intercarrier compensation, which mainly involves call termination rates, and of universal service. Finally, we discuss the economic analysis of two major mergers: AT&T-T-Mobile, which the FCC staff recommended should be referred to an administrative hearing, and Level 3/Global Crossing, which was cleared with no conditions.     

Dynamics of Intraindustry Trade and Labor-Market Adjustment

This paper investigates some dynamic aspects of the 'smooth adjustment hypothesis' that is commonly associated with intraindustry trade (IIT). The analysis is conducted on a panel of plant-level employment data and industry-level production and trade data for Ireland. Rates of intraindustry job turnover are used as a proxy for labor-market adjustment. Three findings stand out. First, a measure of marginal IIT is found to be more appropriate for the analysis of adjustment issues than the traditional static IIT index. Second, the effect of marginal IIT on labor-market adjustment is most significant in the short term, namely for indices calculated on one-year ntervals and lagged by one year. Third, the most significant determinants of the intraindustry job turnover rate are sector-level plant concentration ratios and trade openness.     

Multiple equilibria and limit cycles in evolutionary games with Logit Dynamics

This note shows, by means of two simple, three-strategy games, the existence of stable periodic orbits and of multiple, interior steady states in a smooth version of the Best-Response Dynamics, the Logit Dynamics. The main finding is that, unlike Replicator Dynamics, generic Hopf bifurcation and thus, stable limit cycles, occur under the Logit Dynamics, even for three-strategy games. We also show that the Logit Dynamics displays another bifurcation which cannot occur under the Replicator Dynamics: the fold bifurcation, with non-monotonic creation and disappearance of steady states.
