Saving rates and portfolio choice with subsistence consumption

We analytically show that a common across rich/poor individuals Stone-Geary utility function with subsistence consumption in the context of a simple two-asset portfolio-choice model is capable of qualitatively and quantitatively explaining: (i) the higher saving rates of the rich, (ii) the higher fraction of personal wealth held in risky assets by the rich, and (iii) the higher volatility of consumption of the wealthier. On the contrary, time-variant “keeping-up-with-the-Joneses” weighted average consumption which plays the role of moving benchmark subsistence consumption gives the same portfolio composition and saving rates across the rich and the poor, failing to reconcile the model with what micro data say.     

Planning Gentrification and the ‘Absent’ State in Athens

In times of austerity, gentrification is promoted as a prime investment opportunity capable of reviving stagnating local economies. In Athens, pro‐gentrification policies (using English slogans like ‘Re‐launch Athens’ and ‘Re‐activate Athens’) have become increasingly defined in their targeting of specific areas. Moreover, planning in Greece is characterized by spontaneity, fragmentation and tolerance of speculation, specifically favouring the gentrification process. In many cases, the state's ‘absence’ after promulgation of regeneration projects acts as a clear strategy for inner‐city gentrification. After discussing the emergent relations between state policies on urban intervention and gentrification in the post‐crash era, this article will focus on the peculiarities of the Greek planning system and how these have led to the gentrification of an inner‐city area called Metaxourgio.     

Exploring the determinants of the OSS market potential: The case of the Apache web server

A theoretical framework is proposed for the better understanding of the OSS global diffusion. Following a case study approach, the Apache web server's market potential is estimated, forecasted and examined in terms of the socio-economic factors determining its diffusion, across different economic environments in developed versus developing countries. Market saturation is explored under the prism of three theoretical perspectives: the institutional, the endogenous and the exogenous growth theories. Findings suggest that Apache market saturation levels depend on both endogenous and exogenous to a country factors and that institutional quality plays an important role to the market potential. Implications for theory and public policy are discussed.     

A spatial analysis of provincial corporate income tax responses: evidence from Canada

Abstract.  Using a model of interdependent tax choices, and accounting for equalization entitlements and general transfers, this paper estimates – making use of a spatial econometric framework – corporate income tax-setting functions for all Canadian provincial governments. The results show that there is a statistically significant positive fiscal interaction among a subset of provinces and between all provinces and the federal government. Provincial corporate income taxes are also found to be negatively related to equalization entitlements, general federal transfers, and the federal corporate income tax. A robustness check on the fiscal relationship between Ontario and Quebec verifies the existence of significant bi-directional fiscal interdependencies. The paper also introduces U.S state corporate income taxes as covariates and examines their interaction with Canadian provinces.     

Generalized method of moments and present value tests of the consumption-capital asset pricing model under transactions costs: evidence from the UK stock market

In this paper we test for the inclusion of the bid–ask spread in the consumption CAPM, in the UK stock market over the time period of 1980–2000. Two econometric models are used: first, Fisher’s (in J Appl Econometrics 9:S71–S94, 1994) asset pricing model is estimated by GMM. We obtain plausible values of all the structural parameters and transactions costs. We subsequently test the robustness of our results by extending the VAR approach proposed by Campbell and Shiller (in Rev Financ Stud 1:195–228, 1988). This is achieved with the inclusion of the normalised bid–ask spread as an independent variable in the pricing equation. Overall, the statistical tests are unable to reject the bid–ask spread as an independent explanatory variable in the C-CAPM. In addition, in the VAR specification we find that both the normalised and the absolute bid–ask spread is a significant predictor of the dividend to price ratio. The paper’s main conclusion is that transaction costs should be included in asset pricing models, as they possess independent explanatory power.      

Chained,exact and superlative hedonic price changes: estimates from microdata

Scanner data are used to calculate chained, exact (and superlative) hedonic price indexes for television sets. The data source is available for a wide range of goods, the application providing an example of how this method can be more widely applied. The indexes correspond to constant utility, hedonic cost-of-living indexes. The approach improves on the existing direct method, which takes its estimates directly from the coefficients on time dummies in a hedonic regression. It also improves on the matched model method used by statistical agencies. The differences between actual price changes and exact hedonic quality-adjusted price changes are found to be substantial. Base-period and current-period weighted exact hedonic indexes are similar, thus providing good approximations to a superlative index. Estimates from the direct, dummy variable approach were compared to the superlative indexes. The disparities between the results argue for caution in the use of the direct, dummy variable approach to estimating quality-adjusted price changes.     

A test of stability in a linear altruism model

Linear altruism predicts the estimated preferences to be independent of the subject’s position in the game, if the role allocation is randomly determined, because subjects, in each role, have the same preferences ex ante. We test and reject this hypothesis.     

Institutions and financial dollarization: Indirect effects based on a policy experiment

We provide evidence that institutional improvements lead to lower levels of financial dollarization through previously unidentified channels. These indirect channels operate in addition to the direct impact identified in the literature and further illustrate the importance of institutions for the extent of banking dollarization.     

Discrimination and job search theories for black British young men

The paper examines empirically the relationship between government revenues and expenditures in four European countries: Greece, Spain, Ireland, and Portugal. In relative terms all four may be considered as the poorest members of the European Union. Yet, they present a fairly diverse picture as far as their macroeconomic performance and fiscal position is concerned. The empirical findings from cointegration and causality tests that are reported here indicate that in the case of Greece and Ireland tax and spending decisions are taken simultaneously by the fiscal authority, the tax-and-spend hypothesis is supported in the case of Spain, while absence of any causal ordering between government expenditure and tax revenues has been established for Portugal.
