Testing the higher education-led growth hypothesis in a small island: an empirical investigation from a new version of the Solow growth model

This study employs a new version of the Solow Growth Model in order to investigate the higher education-led growth (HELG) hypothesis in the case of North Cyprus. Results reveal that a long-run equilibrium relationship exists between real income growth of North Cyprus and its determinants, namely capital, labor, and the higher education sector. Results show that real income growth converges to its long-term equilibrium level by 10.9 %. Granger causality tests suggest undirectional causality from higher education growth to real income growth in North Cyprus. Therefore, the HELG hypothesis can be inferred for the Turkish Cypriot economy.     

Gender wage gap studies: consistency and decomposition

This paper reviews the empirical literature on the gender wage gap, with particular attention given to the identification of the key parameters in human capital wage regression models. This is of great importance in the literature for two main reasons. First, the main explanatory variables in the wage model, i.e., measures of work experience and time-out-of-work, are endogenous. As a result, applying traditional estimators may lead to inconsistent parameter estimates. Second, empirical evidence on the gender wage gap hinges on estimates of the parameters of interest. Accordingly, their economic meaning may be limited by restrictive assumptions included in wage models. This challenges both researchers and policymakers who require precise measures of the gender wage gap in order to create and enforce efficient equality policies. This paper is a substantially revised version of the first chapter of my thesis. I am grateful to Christian Dustmann and Wendy Carlin for their great support and comments. I also thank Bernd Fitzenberger, colleagues at the Norwegian School of Economics and Business Administration and IZA, and three anonymous referees for their helpful comments and suggestions.     

Environmental versus Human-Induced Scarcity in the Commons: Do They Trigger the Same Response?

We study appropriation strategies in common pool resources where extinction is a credible threat. Here we present an experimental study of the appropriation of common pool resources in a dynamic setting where resource availability depends on the initial environmental characteristics of the common resource and on human-induced resource depletion due to users’ appropriation patterns. Our results show that initial resource scarcity limits appropriation by inducing an initial caution among users that persists throughout of the game. Additionally, we find that subjects restrain their appropriation strategies when scarcity increases. However, this concern for resource scarcity is not enough to prevent resource depletion. Agents do not counteract the previous rounds’ appropriation strategies but follow the appropriation trend. High appropriation levels are followed by higher appropriation strategies, thus promoting the well known tragedy of the commons. Often concern for resource preservation is not great enough to limit appropriation.      

Second price auctions on general preference domains: two characterizations

Auction theory usually assumes the quasi-linearity of individual preferences. We drop this assumption and define an extension of second price mechanisms that applies to general preferences. It turns out that the extended second price mechanisms are the only rules satisfying efficiency, strategy-proofness, and a mild non-imposition property. Their definition is simple just as much as the definition of usual second price mechanisms: everyone reports his maximum willingness to pay and the bidder whose reported value is highest buys the auctioned object for the price equal to the second highest reported value. The characterization is valid if efficiency is replaced by envy-freeness. I gratefully acknowledge an associate editor and two anonymous referees for their very helpful comments. Hiroki Saitoh and Shigehiro Serizawa independently obtain a result that is closely related to my main result (see, Remark in Sect. 1). I thank them for sending me the paper and communication, and Yuji Fujinaka for informing me about their work. I also thank the financial support by KAKENHI (19310031).     

Liberalisation,competition and ownership in the presence of vertical relations

This contribution analyses a market with an upstream bottleneck monopoly and a downstream activity that may either be vertically integrated or separated. Separation always reduces the consumer surplus, and the total surplus unless there are large cost reductions. Downstream competition from a public or private network monopoly would crowd out other firms, also when public ownership is associated with more modest objectives than welfare-maximisation. A market is therefore less likely to remain a mixed oligopoly than without vertical relations. However, private firms would survive in a moderately welfare-improving mixed oligopoly with cross-subsidisation and access charges equal to marginal costs.

The Eisner Puzzle,the Unemployment Threshold and the Range of Equilibria

Using a two-regime model of the inflation-unemployment process for US data 1960:2 to 2000:2, this paper finds strong evidence to support the Eisner puzzle, which occurs when the short-run Phillips curve (SRPC) is flatter at low rates of unemployment than at higher rates. The puzzling aspect of this pattern is the expectation of excess demand to become apparent at very low rates of unemployment causing the SRPC to be steep rather than fairly flat. We show the puzzle can be resolved by estimating a three-regime model which reveals a steep SRPC at very low rates of unemployment. The estimates of the three regime model also reveal a horizontal SRPC at intermediate rates of unemployment, implying the existence of a range of equilibrium rates of unemployment at those intermediate rates.

Mergers in asymmetric Stackelberg markets

It is well known that the profitability of horizontal mergers with quantity competition is scarce. However, in an asymmetric Stackelberg market we obtain that some mergers are profitable. Our main result is that mergers among followers become profitable when the followers are inefficient enough. In this case, leaders reduce their output when followers merge and this reduction renders the merger profitable. This merger increases price and welfare is reduced.      

Does an Endogenous Relationship Exist between Environmental and Economic Performance? A Resource-Based View on the Horticultural Sector

The aim of this paper is to analyse the relationship between environmental and economic performance from the resource-based theory within firms of the fresh fruit and vegetables sector. This study considers that the adoption of environment-friendly practices has a greater influence on firms’ opportunities and abilities in the agricultural sector than in manufacturing sectors and leads to closer links between performance variables. The reference for this empirical analysis is a panel data of horticultural farming-marketing firms in Spain. The voluntary environmental programmes and the heterogeneity of their application lead us to regard acquiring a competitive advantage as a relevant driver to improve environmental performance in this sector. A simultaneous equations model is suggested reflecting the differential environmental effect and the assumption of endogeneity among variables. The results show a positive impact of environmental differentiation on profitability and market share, also suggesting that the perception of this positive experience implies greater environmental performance.
