This paper uses the experimental method to examine an arbiter's ability to determine the outcome of two-person coordination games. All of the arbiter's assignments in the experiments were strict equilibrium points, but some assignments violated payoff-dominance or symmetry. An assignment that corresponds to the game's outcome is a credible assignment. The experiments test the hypothesis that an assignment to a strict equilibrium is a credible assignment. Our subjects did not find the individual rationality and mutual consistency of an equilibrium assignment to be sufficient reason for implementing the assignment when doing so conflicts with payoff-dominance or symmetry.  相似文献

Models for which the MLE and the conditional MLE coincide   总被引:1,自引:0,他引:1  
The MLE, CMLE and MMLE coincide in a linear regression model with fixed individual effects. In this case, there is no incidental parameters problem and the MLE is consistent. The equivalence of these estimators is important because CMLE=MLE implies both the consistency of the MLE and the efficiency of the CMLE. In general, we cannot expect to find a CMLE or MMLE, since there may be no fixed-dimension sufficient statistic for the effects, nor an appropriate transformation of the data whose distribution does not depend on the effects. However, we show that the MLE, CMLE and MMLE do coincide in systems of seemingly unrelated regressions and in systems of simultaneous equations. We establish this result for systems in which (exogenous) variables in addition to (or other than) the intercept may have coefficients which vary over individuals, provided that the set of such variables is the same in every equation.The financial support of the National Science Foundation is gratefully acknowledged.  相似文献

The paper uses cointegration methods to test the market efficiency hypothesis (MEH) in the foreign exchange markets. Four exchange rates are considered-all relative to the US dollar: BP, DM, SF and JY. Survey data on expectations are used to see whether the violation of the MEH is due to expectational errors or risk premia. The results differ for the one-week ahead and the one-month ahead forecasts. With the weekly data we conclude that it is risk premia, and with the monthly data it is both expectational errors and risk premia that account for the violation of the MEH. Given the volatility of the exchange markets, it appears that forecasts over an extended period fail tests of rationality, but one-week ahead forecasts do not fail such tests.  相似文献

By analysing the different roles of the Indonesian state in arranging finance schemes for palm-oil development since 1945, this article aims to answer two questions: What are these roles? And to what extent have they prioritised or balanced economic growth, social equity, and environmental protection? We conclude that the state has never been absent from the palm-oil industry but has had different and changing financing roles that are historically contingent and shaped by the evolving economic and political landscape. Furthermore, these roles reflect Indonesia’s priorities of achieving economic growth through palm-oil development, furthering social equity, and, recently, promoting environmental sustainability.  相似文献

Mozambique’s tourism sector could play a key role in the country’s socio-economic development, especially in the region of Cabo Delgado where the demand for tourist services is expected to increase. Nonetheless, several constraints (e.g. the lack of adequate training) are hindering the capacity of local people to take full advantage of this opportunity. Qualitative research has been performed in order to align vocational training programmes with the needs of the emerging tourism sector. Local and foreign key informants were interviewed in order to gain a better understanding of training needs and to gain insights into developing training programmes that can enhance local people’s employability. The main findings highlight the lack of symbolisation of tourism and its correlates from local communities. Therefore, rather than just delivering technical skills, training programmes should also promote a ‘culture of tourism’ and a more favourable attitude towards ‘working in the tourism sector’.  相似文献

This paper focuses on developing countries’ pioneer exports to the OECD and obtains several important results on export dynamics, linking export experience and export survival. Using product level data at the SITC 5-digit level for 114 developing countries over the 1962–2009 period, we show that prior export experience obtained in non-OECD markets significantly increases survival of pioneer exports toward the OECD. The experience does not need to last long, as gaining experience for more than two years does not confer any additional benefit. The effect of experience depreciates rapidly with time: a break in export experience prior to entering the OECD reduces the advantage on survival. Finally, the role of prior export experience is particularly relevant for survival in the first two years upon entry into the OECD. The geographic dynamic of export experience reveals that experience is acquired in neighboring, easy to access markets before reaching more distant, richer partners and ultimately serving the OECD with a higher probability of survival.  相似文献

This paper provides fresh estimates of income and price elasticities of import demand in Guyana, Jamaica, and Trinidad and Tobago using a bounds test for cointegration. In addition, the paper also provides estimates of the consumption, investment, and exports elasticities of import demand. These latter elasticities were all found to be positive and statistically significant with values ranging from 0.16 to 0.55 in the long-run.  相似文献

A decision support model (DSM) is presented and implemented in order to identify probable and realistic export opportunities for Greece. The aim of the model is to select those combinations of products and countries of destination (markets) that are attractive based on widely recognized criteria (such as country risk indicators, macroeconomic data, market shares, accessibility of destination country, degree of market concentration, etc.). The DSM consists of a filtering process during which the less attractive export opportunities are successively eliminated in order to focus on those markets that have the desired characteristics. International trade data at the HS six-digit level up to 2011 where used. The results indicate that there exist significant export opportunities for Greece. Export opportunities are listed and categorized according to criteria such as the market characteristics of the destination country and Greece’s market share.  相似文献
