Our objective is to develop a unifying framework for the incorporation of different types of survey data in individual choice models. We describe statistical methodologies that combine multiple sources of data in the estimation of individual choice models and summarize the current state of the art of data combination methods that have been used with market research data. The most successful applications so far have combined revealed and stated preference data. We discuss different types of market and survey data and provide examples of research contexts in which one might wish to combine them. Although these methods show a great deal of promise and have already been used successfully in a number of applications, several important research issues remain. A discussion of these issues and directions for further research conclude the paper.  相似文献

We examine the survival of young scientists in academe. The propensity to leave follows an inverse u-shape. Publishing increases and patenting decreases the chance of survival. Scientists with strong preferences for business are less likely to stay in academe.  相似文献

The current state of affairs in the euro area (EA) instills hope in economic recovery but also substantial concern. The crisis countries have made considerable, albeit quite uneven, progress in central areas of reform. Yet severe obstacles remain. Moreover, European policy makers have reformed the EA’s institutional framework to strengthen its resilience. Yet important elements of a stable architecture are still missing, and it remains unclear whether the EA is moving towards full integration or a Maastricht 2.0. Most importantly, since it has become impossible to construct a viable fi scal bridge due to the success of the OMT programme, now everything depends on the perseverance of domestic reform policies.  相似文献

The present paper uses data from the World Bank Enterprise Survey conducted in Turkey in 2005 to shed light on the firms that use intermediaries in international trade. It lends robust empirical support to recent theories which suggest that indirect exporters are mostly small firms that are not profitable enough to cover the high fixed costs of building an own distribution network abroad. Manufacturers who develop new products are more likely to use trade intermediaries, as are firms that produce low‐quality goods. In contrast, neither foreign ownership nor credit constraints are correlated with the choice of export mode. Moreover, firms that rely on trade intermediaries to sell their goods abroad also do so to source their foreign inputs, implying that the role of intermediaries in facilitating trade may be larger than previous studies suggest.  相似文献

ABSTRACT

We investigate the response of US trucking firms to the removal of barriers to cross-border trucking under NAFTA. This was done via a program implemented in 2007, cancelled in 2009, and reinstated in 2011. We use a model of endogenous exporting to show that this can arise from incorrect expectations of import competition. We find that, unsurprisingly, the program’s start resulted in lower stock returns, particularly for border firms. However, later policy changes indicate that investors, and particularly those investing in US multinationals, viewed the pilot as beneficial.  相似文献

We derive a quantity‐based structural gravity equation system in which both trade flows and error terms are cross‐sectionally correlated. This system can be estimated using techniques borrowed from the spatial econometrics literature. To illustrate our methodology, we apply it to a well‐known Canada–US trade dataset. We find that border effects between the USA and Canada are smaller than suggested by previous studies: about 7.5 for Canadian provinces and about 1.3 for US states. Hence controlling directly for cross‐sectional interdependence among both trade flows and error terms reduces measured border effects by capturing ‘multilateral resistance’.

This paper examines the wood supply from non-industrial private forest owners in Austria. The main novelty of this study is threefold. First, the underlying dataset is based on monthly wood supply. This enables an analysis of seasonal supply behavior, which is found to be different in relation to the size of the forestland. Second, it represents an original study with a dataset from a Central European country whose forest owners are apparently much more fragmented than their Scandinavian or North American counterparts. And third, the study introduces a windfall variable that effectively corrects for a market-relevant storm event. With respect to methodology, a random effects Tobit model is applied. Additionally, a Chamberlain-like term is included in the regression to deal with a possible bias generated through the correlation of regressors and unobserved heterogeneity.  相似文献
