This paper proposes a new panel unit root test based on the generalized method of moments approach for panels with a small number of time periods and a large number of cross-section units, N. In the model that we consider the deterministic trend function is essentially unrestricted and the...

Conventional threshold models contain only one threshold variable. This paper provides the theoretical foundation for threshold models with multiple threshold variables. The new model is very different from a model with a single threshold variable as several novel problems arisefrom having an...

The purpose of this paper is twofold: 1) to highlight the widely ignored but fundamental problem of ‘superpopulations’ for the use of inferential statistics in development studies. We do not to dwell on this problem however as it has been sufficiently discussed in older papers by...

The cleanup of the Mediterranean region constitutes one of the main chapters carried by the cooperation between both north and south banks within the framework of the Union for the Mediterranean (UfM). The subject of this paper is to study the relationship between CO2 emissions and economic...

The different robust estimators for the standard errors of panel models used in applied econometric practice can all be written and computed as combinations of the same simple building blocks. A framework based on high-level wrapper functions for most common usage and basic computational...

This paper applied a stochastic translog production function to examine the underlying causes of technical inefficiency for 28 provinces in the mainland China over the period 1970-2004. We found that inefficiency was present in production and several relevant explanatory variables contributed to...

The objective of this paper represents the analysis of the way the Romania's economic integration in the EU will influence the regional specialization and industrial activities localization within NUTS (the eight regions of Romania) during the period 1991-2004, using absolute measures...

This paper replicates the Johnson et al.’s (1998) empirical analysis of the affects of regulatory discretion on the unofficial economy. The narrow replication uses the data set of the original study which comprises of 49 countries for the year 1997. The wide replication is performed in two...

The economic literature emphasizes the existence of a debate having milked with the impact of the monetary policy on the economic activity. At the beginning of the years 1990, the monetary policy of the countries of the CEMAC knew significant reforms which aimed at conferring to him of advantage...

The paper examines the heterogeneity with respect to the impact of a financial reform - Activity Based Financing (ABF) - on hospital efficiency in Norway. Measures of technical efficiency and of cost-efficiency are considered. The data set is from a contiguous ten-year panel of 47 hospitals...
