Modeling public transport corridors with aggregate and disaggregate demand

Microeconomic public transport models aimed at maximizing social benefits usually consider demand in an aggregate manner. In this paper we examine the effect of this approach on the optimal values of frequency and vehicle size by comparison with models where demand is described in detail as a matrix of flows between every station in a single line service. The theoretical analysis and the numerical examples suggest that the spatially aggregated model underestimates optimal frequency and overestimates vehicle size.     

WINNERS AND LOSERS FROM DOLLAR DEPRECIATION

We examine the relationship between the US current account deficit, the international value of the dollar, and the dollar reserves of foreign central banks. The declining dollar could benefit US savers at the expense of foreign investors in the USA.     

Foreign Acquisition and Firm Productivity: Evidence from Slovenia

This paper investigates the impact of foreign acquisition on the productivity of Slovenian manufacturing firms subject to takeover in 1997. It finds evidence that foreign investors acquire those enterprises with higher productivity, that are more inclined to export and that operate in more concentrated industries. It then controls for the estimation bias induced by this non‐random selection process by applying the combined propensity score matching and difference‐in‐differences estimation technique. The results of the empirical analysis show no robust statistical evidence of a positive causal effect of foreign acquisition up to two years following takeover. This finding suggests that a transfer of intangible assets from foreign firms to their Slovenian affiliates does not take place over this time period.     

NON PURE PRIVATE GOODS IN THE ECONOMICS OF PRODUCTION PROCESSES

In this article the concept of nonrival input is re-examined as a possible source of increasing returns, by taking a production process as the elementary unit of analysis. Nonrivalry of inputs is redefined in order to furnish an analytical tool to be used for extending the theory of value and distribution beyond the case of pure private goods and constant returns. Furthermore, the reformulation of the same concept is implemented for a critical appraisal of the notion of industrial design which has been adopted by Romer in his modelling approach to the theory of endogenous growth.     

Welfare Impacts of Cross-Country Spillovers in Agricultural Research

The welfare implications of intellectual property protection (IPP) for private sector agricultural research are analyzed, focusing on the realistic cases where countries provide different IPP levels, technology spills over across countries, and the public sector is involved in research. A model is developed to determine who benefits from, and who should pay for, the associated research. The article contains some interesting results on the implications of a harmonization of IPP policies through multilateral agreements or via technology that allows research firms to prevent the copying of plants and animals that express traits that have emerged from their research.     

A folk theorem for minority games

We study a particular case of repeated games with public signals. In the stage game an odd number of players have to choose simultaneously one of two rooms. The players who choose the less crowded room receive a reward of one euro (whence the name “minority game”). The players in the same room do not recognize each other, and between the stages only the current majority room is publicly announced. We show that in the infinitely repeated game any feasible payoff can be achieved as a uniform equilibrium payoff, and as an almost sure equilibrium payoff. In particular we construct an inefficient equilibrium where, with probability one, all players choose the same room at almost all stages. This equilibrium is sustained by punishment phases which use, in an unusual way, the pure actions that were played before the start of the punishment.     

Kinked norms of behaviour and cooperation

Using a country panel of domestic terror attacks from 1998 to 2004, we empirically analyze the impact of government decentralization on terror. Our results show that expenditure decentralization reduces domestic terror, while political decentralization has no impact.     

Financing Pay-as-you-go Public Pension Systems: Some Notes in the Light of the Classical-type Theory of Income Distribution

The paper uses a Sraffa-type two-sector model to study how the presence of retired workers interacts with the distribution of the surplus between workers and capitalists (firms). In particular, the paper investigates how the ongoing diminution of the ratio between active and retired workers affects the wage-profits-pensions frontier, which is defined after allowing that a social security tax, which reduces the claims of active workers and capitalists on the surplus of the economy, finances the pensions distributed each year to retired workers. Finally, it is argued that the different impact of defined-benefit and defined-contribution pay-as-you-go pension schemes depends on the actual incidence of payroll taxes.     

Salesperson's listening in buyer–seller service relationships

Research has consistently shown that salesperson's active listening behavior leads to strong sales performance. Yet the influence of management policies on listening has received very limited attention, and prior research linking listening to customer retention has led to mixed findings. This study examines how listening is enhanced through control systems and the influence of listening on customer retention in a service context. Dyadic data from salespeople and their customers show that a behavior-based control system (measured as a second-order construct) positively influences listening and the salesperson's customer orientation totally mediates the influence of listening on customer commitment to the salesperson and loyalty to the service company. Our findings indicate that listening is a necessary but not sufficient condition for assuring relationship development. More specifically, customer orientation is the generative mechanism through which listening is able to influence customer retention. Theoretical and practical implications are discussed.
