Equilibria in an overlapping generations model with transfer policies and exogenous growth

For an overlapping generations economy with varying life-cycle productivity, non-stationary endowments, continuous time starting at $-\infty $ (hence allowing for full anticipation), constant-returns-to-scale production and ces utility, we fully characterise equilibria where output is higher than investment, which is strictly positive. Net assets (aggregate savings minus the value of the capital stock) are constant in any equilibrium, and, for balanced growth equilibria (bge, defined for an economy with stationary endowments), net assets are non-zero only in the golden rule equilibrium, in accord with Gale (1973). The number of bge is finite. Their parity, however, depends on the life-cycle productivity, in particular, on the relation between the intertemporal elasticity of substitution, the minimal working age and the minimal tax age.     

Is per capita real GDP stationary in five southeastern European countries? Fourier unit root test

This study uses the newly developed Fourier unit root test advanced by Enders and Lee (2004, 2009) to investigate the time-series properties of real GDP (Gross Domestic Product) for five Southeastern European countries for the period from 1969 to 2009. The empirical results from several conventional unit root tests indicate that the per capita real GDP for all of the countries studied are non-stationary; however, when Enders and Lee (2004, 2009) Fourier unit root tests are conducted, one rejects the unit root hypothesis of real GDP per capita in all countries under study. These results have important policy implications for these five Southeastern European countries under study.     

Eco-Efficiency and Convergence in OECD Countries

This paper assesses the convergence in eco-efficiency of a group of 22 OECD countries over the period 1980–2008. In doing so, three air pollutants representing the impact on the environment of economic activities are considered, namely, carbon dioxide ( ${\text{ CO}}_{2}$ ), nitrogen oxides ( ${\text{ NO}}_\mathrm{X}$ ) and sulphur oxides ( ${\text{ SO}}_\mathrm{X}$ ); furthermore, eco-efficiency scores at both country and air-pollutant-specific level are computed using Data Envelopment Analysis techniques. Then, convergence is evaluated using the recent approach by Phillips and Sul Econometrica 75:1771–1855 (2007), which tests for the existence of convergence groups. First, we find that eco-efficiency has improved over the period, with the exception of ${\text{ NO}}_\mathrm{X}$ emissions. Second, Switzerland is the most eco-efficient country, followed by some Scandinavian economies, such as Sweden, Iceland, Norway and Denmark. In contrast, Southern European countries such as Portugal, Spain and Greece, in addition to Hungary, Turkey, Canada and the United States, are among the worst performers. Finally, we find that both the most eco-efficient countries and the worst tend to form clubs of convergence.     

Outsourcing versus technology transfer: Hotelling meets Stackelberg

We consider a Hotelling duopoly with two firms $A$ and $B$ in the final good market. Both can produce the required intermediate good, firm $B$ having a lower cost due to a superior technology. We compare two contracts: outsourcing ( $A$ orders the intermediate good from $B$ ) and technology transfer ( $B$ transfers its technology to $A$ ). An outsourcing order is equivalent to building an endogenous capacity and it generates a Stackelberg leadership effect for firm $A,$ which is absent in technology transfer. We show that compared to the situation of no contracts there are always Pareto improving outsourcing contracts (making both firms better off and all consumers at least weakly better off), but no Pareto improving technology transfer contracts. It is also shown that if firm $B$ has a relatively large bargaining power in its negotiations with $A,$ then both firms prefer technology transfer while all consumers prefer outsourcing.     

More equal but not so fair: an analysis of Brazilian income distribution from 1995 to 2009

This study measures unfair inequality in Brazil between 1995 and 2009. To achieve that, we used the statistical tool developed by Almås et al. (J Public Econ 95:488–499, 2011) and the concept of “responsibility-sensitive” fairness proposed by Bossert (Math Soc Sci 29:1–17, 1995), Konow (J Econ Behav Organ 31(1):13–35, 1996) and Cappelen and Tungodden (Fairness and the proportionality principle, Discussion paper SAM 31/2007. Norwegian School of Economics and Business Administration, 2007). The results indicate that the fairness level in Brazil remained unchanged throughout the analyzed period.     

Removing biases in forecasts of fishery status

A recent highly cited paper from this journal develops a model predicting maximum sustainable yield ( \(MSY\) ) of a fishery using the historical maximum catch ( \(MaxCatch\) ). The model is parameterized with a small sample of fisheries from the United States, and is subsequently applied globally to estimate the benefits of fishery recovery. That empirical relationship has been adopted for many subsequent high-profile analyses. Unfortunately, the analysis suffers from two important oversights: (1) because the model is non-linear, it suffers from “retransformation bias” and therefore the results significantly understate \(MSY\) and (2) the analysis is parameterized from of a very limited data set and so generalizability of the fitted empirical relationship between \(MSY\) and \(MaxCatch\) to global fisheries is questionable. Here, we rectify both oversights and provide an updated estimate of the relationship between \(MSY\) and \(MaxCatch\) .     

Interrelationships among banks,stock markets and economic growth: an empirical investigation

This article utilizes a simultaneous equations model to study the relationships among economic growth, banking and stock market development. In contrast to conventional instrumental variable approach, we implement the analysis via the methodology of identification through heteroscedasticity. Using Beck and Levine (2004 Beck, T. and Levine, R. (2004) Stock markets, banks and growth:panel evidence, Journal of Banking and Finance, 28, 423–42.[Crossref], [Web of Science ®] , [Google Scholar]) dataset, we find that each of the three variables interacts in important ways. While both are conducive to economic growth, banking development matters more for growth in low-income countries and stock market development is more favourable to growth in high-income or low-inflation ones. The data also reveal coexistence of a positive effect of banking development on stock market development and a negative effect of stock market development on banking development. Besides, the feedback effects of growth on both banking and stock market development are found.     

Essential data, budget sets and rationalization

According to a minimalist version of Afriat’s theorem, a consumer behaves as a utility maximizer if and only if a feasibility matrix associated with his choices is cyclically consistent. An “essential experiment” consists of observed consumption bundles $(x_{1}, \ldots , x_{n})$ and a feasibility matrix $\varvec{\alpha }$ . Starting with a standard experiment, in which the economist has access to precise budget sets, we show that the necessary and sufficient condition for the existence of a utility function rationalizing the experiment, namely, the cyclical consistency of the associated feasibility matrix, is equivalent to the existence, for any budget sets compatible with the deduced essential experiment, of a utility function rationalizing them (and typically depending on them). In other words, the conclusion of the standard rationalizability test, in which the economist takes budget sets for granted, does not depend on the full specification of the underlying budget sets but only on the essential data that these budget sets generate. Starting with an essential experiment $(x_{1}, \ldots , x_{n}; \varvec{\alpha }$ ) only, we show that the cyclical consistency of $\varvec{\alpha }$ , together with a further consistency condition involving both $(x_{1}, \ldots , x_{n})$ and $\varvec{\alpha }$ , guarantees the existence of a budget representation and that the essential experiment is rationalizable almost robustly, in the sense that there exists a single utility function which rationalizes at once almost all budget sets which are compatible with $(x_{1}, \ldots , x_{n}; \varvec{\alpha }$ ). The conditions are also trivially necessary.     

Restrictions and identification in a multidimensional risk-sharing problem

We consider $H$ expected utility maximizers that have to share a risky aggregate multivariate endowment $X\in {\mathbb {R}}^{N}$ and address the following two questions: does efficient risk-sharing imply restrictions on the form of individual consumptions as a function of $X$ ? Can one identify the individual utility functions from the observation of the risk-sharing? We show that when $H\ge \frac{2N}{N-1}$ efficient risk sharings have to satisfy a system of nonlinear PDEs. Under an additional rank condition, we prove an identification theorem.     

Consistent strategy-proof assignment by hierarchical exchange

We characterize the family of efficient, consistent, and strategy-proof rules in house allocation problems. These rules follow an endowment inheritance and trade procedure as in Pápai’s hierarchical exchange rules (Pápai in Econometrica 68, 1403–1433, 2000) and closely resemble Ergin’s priority rules (Ergin in Econometrica 70, 2489–2497, 2002). We prove that if there are at least four objects, these are the only rules that are efficient in two-agent problems, $2$ -consistent, and strategy-proof. A corollary is that these three basic properties together imply the full requirements of efficiency, consistency, group strategy-proofness, and reallocation-proofness.     

Does PPP hold in African countries? Further evidence based on a highly dynamic non-linear (logistic) unit root test

With a view to investigating whether the purchasing power parity (PPP) theory holds true for selected African countries during the January 1980–December 2003 period, we employ a rigorous, highly dynamic non-linear (logistic) unit root test, as first advanced by Leybourne et al. (1998 Leybourne, S, Newbold, P and Vougas, D. 1998. Unit roots and smooth transitions. Journal of Time Series Analysis, 19: 83–97. [Crossref] , [Google Scholar]), which is considerably more powerful than those tests traditionally used. Compared with the rejection of the null of the unit root process for only one of the 22 countries under study when we use the traditional ADF, PP, KPSS, NP and the DF-GLS unit root tests, with the Leybourne et al. (1998 Leybourne, S, Newbold, P and Vougas, D. 1998. Unit roots and smooth transitions. Journal of Time Series Analysis, 19: 83–97. [Crossref] , [Google Scholar]) test, we strongly reject the null of the unit root process for a surprising six of the 22 countries. These empirical results clearly indicate that PPP holds true for these six countries, namely the Central African Republic, the Côte d’Ivoire, Kenya, Madagascar, Uganda and Lesotho.     

Financialization and the rentier income share – evidence from the USA and Germany

During the past two decades, there has been a shift of significance from the real to the financial sector. In the course of (financial) globalization, measures of liberalization and deregulation have contributed to a strengthening of financial capital. The concept of shareholder value orientation has become more powerful, capital income has increased tremendously, while real wages have stagnated. Most industrial countries have experienced a decline in the share of labor income. Based on a review of empirics and literature, this paper seeks to determine who gained from the fall in the labor share of income in the USA and Germany, respectively. If financialization is indeed responsible for the decline, rentiers should be the beneficiaries. In order to identify the relevant effects, the profit share of the two countries under observation is split between the share of retained earnings and the share of net property income (= rentiers’ income) using a modification of the approach chosen by Epstein and Jayadev (2005 Epstein, G. and Jayadev, A. 2005. “The rise of rentier incomes in OECD countries: Financialization, central bank policy and labor solidarity”. In Financialization and the world economy, Edited by: Epstein, G. Cheltenham: Edward Elgar.  [Google Scholar]). The evidence presented shows that the development of the rentier income share indeed corresponds quite well with the stages of development of financialization in the two different countries: in the US, where the important shift towards financialization occurred in the early 1980s, the rentiers’ share of income shows a corresponding leap upwards exactly at that time and remains on a higher level until the end of the observation period. In Germany, the process of financialization started much later – in the beginning of the 1990s – and followed a much more gradual transition, which is perfectly mirrored by the development of income shares: from the 1990s onwards, the rentiers’ income share gradually increased over time.     

Forecasting spatially dependent origin and destination commodity flows

We explore origin–destination forecasting of commodity flows between 15 Spanish regions, using data covering the period from 1995 to 2004. The 1-year-ahead forecasts are based on a recently introduced spatial autoregressive variant of the traditional gravity model. Gravity (or spatial interaction models) attempt to explain variation in \(N = n^2\) flows between \(n\) origin and destination regions that reflect a vector arising from an \(n\) by \(n\) flow matrix. The spatial autoregressive variant of the gravity model used here takes into account spatial dependence between flows from regions neighboring both the origin and destinations during estimation and forecasting. One-year-ahead forecast accuracy of non-spatial and spatial models are compared.     

Institutions and growth: evidence from estimation methods robust to weak instruments

This article focuses on the empirical approach proposed by Hall and Jones (1999 Hall, RE and Jones, CI(HJ99). 1999. Why do some countries produce so much more output per worker than others?. The Quarterly Journal of Economics, 114: 83–116. [Crossref], [Web of Science ®] , [Google Scholar]) to estimate the effect of what they call ‘social infrastructure’ on productivity across countries. We consider the issue of weak identification in their linear instrumental variables model. The evidence obtained from partially robust estimators, such as the k-class and jackknife estimators, is interpreted on the basis of Monte Carlo studies. Our findings suggest that using certain k-class estimators allows exclusive reliance on the linguistic variables to instrument for institutional quality despite their low correlation with the endogenous regressor in question.     

The role of permanent and transitory components in the fluctuations of Latin–American real exchange rates

Following the approach suggested by Engel and Kim (1999 Engel, C. 1999. Accounting for U.S. real exchange rates changes. Journal of Political Economy, 107: 507–38. [Crossref], [Web of Science ®] , [Google Scholar]), we estimate the permanent and transitory components of the real exchange rates in four Latin–American countries for the period 1957:01 to 2002:04. Results suggest that transitory component is the driving force of the real exchange rates in Argentina and Mexico. A principal role of the permanent component is observed in the real exchange rates of Brazil and Chile. Estimates probabilities of the high-variance regime allow to identify the principal events happened in these countries. This information is closely related to nominal shocks and therefore, it explains the significant role of this component in these countries.     

Information and \sigma -algebras

In this work, we clarify the relationship between the information that an agent receives from a signal, from an experiment or from his own ability to determine the true state of nature that occurs and the information that an agent receives from a $\sigma $ -algebra. We show that, for countably generated $\sigma $ -algebras, the larger it is, the larger the information is. The same is true for general $\sigma $ -algebras after the removal of a negligible set of states.     

Motivating energy suppliers to promote energy conservation

We examine the design of regulatory policy to induce electric utilities to deliver the surplus-maximizing level of energy efficiency services, $e^{*}$ . The rebound effect (whereby increased energy efficiency stimulates the demand for energy) typically renders revenue decoupling insufficient in this regard. The additional financial incentive required to induce $e^{*}$ is shown to vary with such factors as the prevailing price of energy, the magnitude of the rebound effect, the extent of observable energy efficiency investments, and the utility’s objective.     

Institutional stickiness of democracy in post-communist states: Can prevailing culture explain it?

Structural explanation of political development offers a finite set of factors that cause democracy to consolidate or not (Acemoglu and Robinson 2006). This approach is, however, insufficient to explain political development of post-communist countries because it ignores a role of social arrangements in democratic consolidation. The field of comparative political economy is becoming more acceptable to the idea that social institutions have significant impact on political development (Boettke et al. Review of Austrian Economics 18(3–4): 281–304, 2005). Using transitional experience of post-communist countries, I demonstrate that institutional stickiness of democracy depends on a combination of causal factors, including underlying political culture (Boettke et al. American Journal of Sociology and Economics 67(2), 2008; Pejovich The Review of Austrian Economics 16(4):347–361, 2003).     

Semantics for intuitionistic epistemic logics of shallow depths for game theory

Epistemic logic of shallow depths has been developed by Kaneko–Suzuki using classical logic. In this paper, we adopt intuitionistic logic as the base logic to limit each player’s reasoning to constructive one. The resulting logical system is denoted by IG $_{EF}$ , and we introduce epistemic possible world semantics for IG $_{EF}$ . We show the soundness and completeness of IG $_{EF}$ with respect to this semantics for it. We also show some applications to game theoretical decision making.
