Behavioural equilibrium exchange rate and total misalignment: evidence from the euro exchange rate

In the present paper we attempt to investigate whether the nominal exchange rate of the euro against the currencies of the four major trading partners of the eurozone, namely China, Japan, the UK and the USA, converges or not to its equilibrium level. Applying recent unit root and system cointegration techniques in the presence of structural shifts in the data, our results indicate that there exist an equilibrium relationship between each of the euro/yuan, euro/yen, euro/UK pound and euro/US dollar nominal exchange rates and the fundamentals defined by the monetary model. Following these results, our modified Behavioural Equilibrium Exchange Rate model suggests that at the end of the estimated period, the euro/Chinese yuan and the euro/UK pound nominal exchange rates follow an equilibrium process. Our empirical results also imply that the single European currency is considered as overvalued against the US dollar, while it is considered as undervalued against the Japanese currency.     

How do Markets Manage Water Resources? An Experiment

We experimentally test how a private monopoly, a duopoly and a public utility allocate water of differing qualities to households and farmers. Most of our results are in line with the theoretical predictions. Overexploitation of the resources is observed independently of the market structure. Stock depletion for the public utility is the fastest, followed by the private duopoly and private monopoly. On the positive aspects of centralized public management, we find that the average quality to price ratio offered by the public monopoly is substantially higher than that offered by the private monopoly or duopoly.     

Cooperative R&D with Endogenous Technology Differentiation

We study a nontournament R&D duopoly. Before the standard R&D investment and quantity-setting stages, we consider a stage in which firms choose their R&D technologies. Spillovers negatively depend on R&D technology differentiation. We show that, in equilibrium, firms will choose identical or very similar R&D processes. Such equilibria may entail less differentiation than would be dictated by social welfare maximization.     

Performance aspects of Greek bond mutual funds

This paper examines the performance characteristics of Greek bond funds and the impact of fund flows on portfolio returns. The evidence shows that on average bond funds do not offer risk-adjusted profits exceeding the returns of the benchmark index, which is in consistence with the US and international evidence. Returns before fees are slightly superior to the returns of the benchmark index, but when fees are considered they lag considerably. The security selection and market timing skills of fund managers are also tested using both an unconditional and a conditional model to test for the impact of public information variables. We also find that fund flows impact negatively on market timing.     

Factor inputs in U.S. trade

This paper focuses on some open questions in the empirical literature on the factor content of U.S. trade. In a regression analysis on 1963 and 1967 cross-section data, it is found that U.S. trade is exporting the services of human capital and importing the services of raw labor and (marginally) of physical capital. The results are not sensitive to scaling for industry size or to using probit analysis rather than OLS regression. An important implication of the results is that it is inappropriate to aggregate physical and human capital in trade models.     

Testing for efficiency in selected developing foreign exchange markets: An equilibrium-based approach

This paper proposes an alternative way of testing FOREX efficiency for developing countries. The FOREX market will be efficient if fully reflects all available information. If this holds, the actual exchange rate will not deviate significantly from its equilibrium rate. Moreover, the spot rate should deviate from its equilibrium rate by only transitory components (i.e. it should follow a white noise process). This test is applied to three Central and Eastern European Countries — members of the EU. Considering an LSTAR model we find no evidence of nonlinear adjustment in the misalignment series. So, linear unit root tests imply that the Poland/Euro FOREX market is efficient, the Czech/Euro FOREX market is not, while the Slovak/Euro FOREX market is quasi-efficient.     

Inter-gender interaction and communication in ultimatum games

In this article, we focus on bargaining within male–female pairs, the most pervasive partnership in humankind. We analyse data from an ultimatum game played by Greek participants. Parallel to this, we introduce a one-way communication protocol according to which the responders can send short messages to the receivers, after making their decisions. The analysis shows that gender and message effects exist and males are more effective bargainers.     

Pro-competitive Price Beating Guarantees: Experimental Evidence

We report experimental results on duopoly pricing with and without price beating guarantees (PBG). In two control treatments, price beating is either imposed as an industry-wide rule or offered as a business strategy. Our major finding is that when price beating guarantees are imposed as a rule or offered as an option, effective prices are equal to or lower than those in a baseline treatment in which price beating is forbidden. Also, when price beating is treated as a business strategy, less than 50% of subjects adopted the guarantee, suggesting that, subjects realize the pro-competitive effects of the guarantee.

Foreign Direct Investment and Exports with Growing Demand

We explore entry into a foreign market with uncertain demand growth. A multinational can serve the foreign demand by two modes, or by a combination thereof: it can export its products, or it can create productive capacity via foreign direct investment (FDI). The advantage of FDI is that it allows for lower marginal cost than exporting does. The disadvantage is that FDI is irreversible and, hence, entails the risk of creating under-utilized capacity in the case that the market turns out to be small. The presence of demand uncertainty and irreversibility gives rise to an interior solution, where the multinational, under certain conditions, both exports its products and does FDI.
