Trust and economic growth: a robustness analysis 总被引:8,自引:0,他引:8

This paper analyses the robustness of results on the relationshipbetween growth and trust previously derived by Knack and Keefer(1997) and Zak and Knack (2001) along several dimensions, acknowledgingthe complexity of the concept of robustness. Our results showthat the Knack and Keefer results are only limitedly robust,whereas the results found by Zak and Knack are highly robustin terms of significance of the estimated coefficients and reasonablyrobust in terms of the estimated effect size. The improvementin robustness is caused by the inclusion of countries with relativelylow scores on trust (most notably, the Philippines and Peru).Overall, our results point at a relatively important role fortrust. However, the answer to the question how large this payoffactually is depends on the set of conditioning variables controlledfor in the regression analysis andto an even larger extentonthe underlying sample. 相似文献

Si dimostrano condizioni necessarie e sufficienti relative a punti di Kuhn-Tucker per il «problema dei dadi truccati» e viene proposto un algoritmo per la ricerca di tali punti, tramite una successione di programmi lineari.
The author's version of the «loaded dice problem» asks for x1 to be maximum subject tox0 andx T H i x1, whereH i is the Hankel matrix of the (2n–1)-dimensional unity vectore i (i=1,..., 2n–1).Proofs are given here about necessary and sufficient conditions for Kuhn-Tucker points, together with an algorithm for finding them by means of a sequence of linear programs.相似文献

The nature and form of the restrictions implied by the rational expectations hypothesis are examined in a variety of models with expectations and the properties of appropriate test statistics are analyzed with Monte Carlo evidence. Specifically, we consider the implications of lagged variables, simultaneous equations, and future period expectations upon the number and functional form of the rational expectations restrictions. Two asymptotically equivalent test statistics — a likelihood ratio and a Wald test — are available for implementing a test of these restrictions. Monte Carlo evidence is offered to provide a comparison between the properties of the alternative test statistics in small samples. 相似文献

This study presents a full model of the labor market under imperfect information. Workers bear the burden of search and are assumed to use a stochastic variant of an optimal sample size search strategy. The existence and uniqueness of a nondegenerate equilibrium distribution of wage offers is established. Infficiencies which lead to underinvestment in search are uncovered and analyzed. 相似文献
