This paper proposes to reexamine the GATT/WTO membership effect on bilateral trade flows, using nonparametric methods including pair-matching, permutation tests, and a Rosenbaum (2002) sensitivity analysis. Taken together in a coherent manner, these methods provide an estimation framework that is robust to misspecification biases, allows general forms of heterogeneous treatment effects, and add...

This paper examines the effects of microfinance, financial development and foreign aid on income inequality for 43 Sub-Saharan African (SSA) countries. Panel data period 1995–2015 is examined using fixed effects, pooled ordinary least square system generalized method moments (GMM) estimation techniques. Findings suggest that although plays a determining role in explaining dynamics SSA, it does ...

Most econometric methods for testing the proposition of long-run monetary neutrality rely on the assumption that money and real output do not cointegrate. This paper argues that these results can be attributed in part to the low power of univariate tests, and that a violation of the noncointegration assumption is likely to result in a nonrejection of the neutrality proposition. To alleviate thi...

In this article we analyze the determinants of the functional distribution of government expenditure using for this purpose the models of the median voter's demand common in public choice literature. First of all, we review the economic literature on the factors affecting each component of government expenditure. Then, secondly, we develop a demand model of expenditure structure and we estimate...

Using company account data for the US and four European countries this paper analyses the impact of ICT spillovers on companies’ performance. We use different definitions of spillovers to account for inter and intra-industry spillover effects, as well as assessing the presence of spillovers from the US to Europe. We also look at the possibility that spillovers might take some time to materialis...

We develop a hierarchical Bayesian approach for inference in random coefficient dynamic panel data models. Our approach allows for the initial values of each unit’s process to be correlated with the unit-specific coefficients. We impose a stationarity assumption for each unit’s process by assuming that the unit-specific autoregressive coefficient is drawn from a logitnormal distribution. Our me...

Crime, Prosecutors, and the Certainty of Conviction This paper tests predictions of a structural, augmented supply-of-offenders model regarding the relative effects of police, public prosecution and courts, respectively, on crime. Using detailed data on the different stages of the criminal prosecution process in Germany, empirical evidence suggests that public prosecutors and their influence on...

The stochastic frontier model used for continuous dependent variables is extended to accommodate output measured as a discrete ordinal outcome variable. Conditional on the inefficiency error, the assumptions of the ordered probit model are adopted for the log of output. Bayesian estimation utilizing a Gibbs sampler with data augmentation is applied to a convenient re-parameterisation of the mod...

The consensus of the aid effectiveness literature is that foreign aid is effective at spurring economic growth in recipient countries. However, economic growth is heterogeneous in nature, driven by a number of different activities within an economy. This paper contributes to the literature by disaggregating the Gross Domestic Product of recipients in order to investigate the type of economic gr...

This paper argues that the Phillips curve–wage curve controversy cannot be settled within the conventional testing frameworks and suggests an alternative test, which builds on the model of Blanchard and Katz (1997). Using long macro data for the OECD countries, the evidence gives very strong support for the Phillips curve and indicates that wage behaviour is no different among the OECD countrie...
