On the joint Fourier–ESTAR testing of PPP

The purchasing power parity (PPP) is the hypothesis that the real exchange rate series are stationary. This study briefly reviews and applies six competing unit root test procedures to test PPP. Reflecting the existing literature, the results are mixed. The Kiliç test is the most favourable while the Kapetanios, Shin, and Snell (KSS) test is the least favourable to PPP and the standard ADF test lies in between. The same conclusion applies to the Fourier extensions of those three tests. The results support a recently suggested F-test for the significance of Fourier terms in unit root test equations.     

A dynamic stakeholder model: An Other‐oriented ethical approach

In this paper, we reflect on the role of the Other in ethical decision‐making in corporations. The Other, in the form of a corporation's stakeholders, has already been discussed in the scientific literature, but there are still some Others that remain unconsidered and that call on corporations to be responsible. Drawing on the philosophy of Levinas, we wish to highlight a green earth and future generations as two non‐immediate Others within a corporation's group of stakeholders whose voices are silenced. We argue that Levinasian ethics can be used as a framework to extend traditional stakeholder theory in a dynamic sphere. With this model, corporations can understand the vital role that both a green earth and future generations play in their existence and can respond to contingencies by considering delays. We enrich our paper with illustrative cases to present some serious environmental disasters that have occurred as a result of ignoring the Other. Finally, we show that understanding the Other as a part of a corporation's identity can create new avenues for “infinite responsibility” towards Others. We contribute to the relevant literature by highlighting that both a green earth and future generations are important but ignored stakeholder parties whose claims urgently need to be addressed.     

The tax-spending nexus: Evidence from a panel of US state-local governments

We re-examine the tax-spending nexus using a panel of 50 US state-local government units between 1963 and 1997. We find that, unlike tax revenues, expenditures adjust to revert back to a long-term equilibrium relationship. The evidence on the short-term dynamics is also consistent with the tax-and-spend hypothesis. One implication of this finding is that the size of the government at the state-local level is not determined by expenditure demand, but rather by resource supply. This is consistent with the fact that many US state and local governments operate under constitutional or legislative limitations that seek to constrain deficits.     

LINK BETWEEN DOMESTIC R&D AND INFLOW OF FDI: A GAME-THEORETIC ANALYSIS

Abstract.  The empirical literature has generated mixed correlations between research and development (R&D) undertaken by domestic firms and the inflow of foreign direct investment (FDI) by their multinational rivals. Further, the existing theoretical explanations of such empirical results appear to be inadequate. This study presents an alternative game-theoretic explanation for the observed correlations. The results show that the seemingly contradictory observed mixed correlations can be explained in an encompassing model in terms of the multinationals' competitive and interactive assessment of the efficiency and expenditure consequences that domestic R&D could generate for the undertaking domestic competitors.     

External debt,time preference,and nontraded goods in a two-sector dynamic model of consumption

A number of studies have indicated that one of the consequences of a development process is a rise in the consumers' subjective time preference rate (discount rate). This study first shows that many of the adverse economic observations in developing countries can emerge from a rise in the discount rate. It then demonstrates that the extent of such adverse effects is related to relative shares of the tradable and nontradable sectors in aggregate consumption. A result is that the aggregate dissaving generated by a rise in the discount rate is smaller when the economy's nontradable sector is relatively larger. The results add new dimensions to the allocation policies applied by international lending insitutions in developing economies.
