The classical stochastic frontier panel data models provide no mechanism to disentangle individual time invariant unobserved heterogeneity from inefficiency. Greene (2005a, b) proposed the so-called “true” fixed-effects specification that distinguishes these two latent components. However, due to the incidental parameters problem, his maximum likelihood estimator may lead to biased variance estimates. We propose two alternative estimators that achieve consistency for with fixed . Furthermore, we extend the Chen et al. (2014) results providing a feasible estimator when the inefficiency is heteroskedastic and follows a first-order autoregressive process. We investigate the behavior of the proposed estimators through Monte Carlo simulations showing good finite sample properties, especially in small samples. An application to hospitals’ technical efficiency illustrates the usefulness of the new approach. 相似文献

In this paper, we study the determinants of the spread charged by banks under a UK policy intervention scheme, aimed at supporting access to the credit market for small firms through guarantee backed loans. We exploit a unique dataset containing data on 29,266 guarantee backed loans under the UK SFLG scheme over the period 2000 to 2005. Results suggest that lower spreads are offered for loans of larger amounts and higher durations, for service firms, for larger firms, and for those located in the most advanced regions. Higher spreads are applied to high-tech manufacturing firms and to loans issued for working capital purposes. We also find that the presence of other extant debt is associated with a relatively higher spread and that this effect is especially significant for the subset of firms that have reached a maximum debt capacity based on collateralized assets. Further, we also find that the higher the incidence of the publicly guaranteed debt over the total amount of outstanding loans, the lower, on average, the spread. However, an increase in the guaranteed coverage leads to a contraction in the spread only for loans aimed at covering working capital needs rather than investments. 相似文献

This paper presents a model to explain the official discount rate of the Central Bank of Austria–Hungary from 1876 to 1913.
The discount rate is assumed to depend on the liquidity ratio of the Bank, defined as the ratio of its stock of metals to
banknotes issued, and on changes in foreign discount rates. The paper also presents an equation explaining the liquidity ratio.
We use “not equally spaced chronologically ordered data” referring to the 50 discount rate changes enacted. The regressions
confirm that the liquidity ratio was the main determinant of the discount rate and that Germany (and not Great Britain) played
a significant role in determining the Austro–Hungarian discount rate and the liquidity ratios, supporting the view that the
classical gold standard was a decentralized multipolar system rather than a system fully dominated by London as suggested
by Keynes. The regressions also suggest that, although Austria–Hungary had an inconvertible paper currency (1879–1892) and
fluctuating exchange rates (1876–1895) and formally joined the gold standard only in 1902, it “shadowed” the behaviour of
gold standard Central Banks with such consistency that the stability of the estimated regressions was relatively unaffected
by the frequent institutional changes.

Empirical work on the relationship between political corruption and the design of public institutions suggests that the structure of judiciaries is an important determinant of corruption. This study develops a simple political economic model to investigate the role of judicial oversight in the policy‐making process for corruption deterrence, focusing on two dimensions of quality of the judiciary, namely efficiency and integrity. Our analysis explicitly accounts for the possibility that, while being independent of the political authority, the judiciary itself may be vulnerable to pressure from special interests. We study endogenous policy‐making under complete information and provide general conditions for the existence of deterrence (zero‐bribe) equilibria. In particular we show that preserving the independence of judiciaries in corrupt societies proves crucial to the existence of corruption‐deterrence effects. 相似文献

We explore the hypothesis that long‐term commitments affect the dynamics of government expenditure. With the aid of a simple median‐voter model we interpret the pattern of increasing‐then‐constant tax rates observed in OECD countries in the second half of the last century: persistence of public expenditure and a lower bound on new interventions will push government size upward, and preferences of the electorate put a halt to this growth at some point. In this view, the fiscal policy variable is seen to consist of only a part of the total expenditure, the rest being predetermined by its past level. 相似文献

This paper contributes to the analysis of the persistence of innovation activities, as measured by total factor productivity (TFP), and explores its internal and external determinants stressing its path-dependent characteristics. The external conditions, namely the quality of local knowledge pools and the strength of the Schumpeterian rivalry, along with the internal conditions (the actual levels of dynamic capabilities, as proxied by wage levels and firm size) exert a specific and localised effect upon the persistent introduction of innovations. A multiple transition probability matrixes (MTPMs) approach has been implemented to capture the contingent effects of external factors on long-term innovation persistence. The empirical analysis of the dynamics of firm-level TFP for a sample of approximately 7000 Italian manufacturing companies observed during the years 1996–2005 is based on both the comparison of different transition probability matrixes and on dynamic discrete choice panel data models. The evidence provided by the test of MTPMs in sub-periods suggests that innovation persistence is path-dependent, as opposed to past-dependent. 相似文献

Supplier evaluation has assumed a strategic role in determining competitiveness of large manufacturing companies. An increasing number of researches have been devoted to the development of different kind of methodologies to cope with this problem. Nevertheless, while the number of applications is growing, there is little empirical evidence of the practical usefulness of such tools with a dichotomy between theoretical approaches and empirical applications. Considering this evidence, the goal of this paper is to contribute to understand the above dichotomy by implementing, in a corporate environment, a model for supplier evaluation based on the Analytical Hierarchical Process (AHP), one of the most prominent methodologies used to address the problem. The analysis of the implementation process of the methodology allows the identification of strengths and weaknesses of using formalized supplier selection models to tackle the supplier evaluation problem, also highlighting potential barriers preventing firms to adopt such methods. Relevant issues arising from the application and managerial implications for both customer and suppliers are discussed. 相似文献

International posting of workers and mobility of self‐employed service suppliers lie between outright migration and trade in goods: their regulation, for both distributional and market‐correcting purposes, is not as difficult to harmonise as that of labour markets, but personal mobility is more visible and socially intrusive than product market interactions. This paper analyses economic and legal tensions between national regulatory frameworks and international competition in these areas, in both the intra‐EU and global contexts, highlighting how interactions between the external and internal roles of the European Commission may foster efficient integration of markets and policies in this and other fields. 相似文献

We investigate how perceived parents’ performance in entrepreneurship (PPE) affects the entrepreneurial career intentions of offspring. We argue that while perceived PPE enhances offspring’s perceived entrepreneurial desirability and feasibility because of exposure mechanisms, it inhibits the translation of both desirability and feasibility perceptions into entrepreneurial career intentions due to upward social comparison mechanisms. Thus, perceived PPE acts as a double-edged sword for the intergenerational transmission of entrepreneurship. Our predictions are tested and confirmed on a sample of 21,895 individuals from 33 countries. This study advances the literature on intergenerational transmission of entrepreneurship by providing a foundation for understanding the social psychological conditions necessary for such transmission to occur. 相似文献
