In this paper we are concerned with the issue of the existence of locally uniform Edgeworth expansions for the distributions of parameterized random vectors. Our motivation resides on the fact that this could enable subsequent polynomial asymptotic expansions of moments. These could be useful...

In this paper we are concerned with the issue of the existence of locally uniform Edgeworth expansions for the distributions of random vectors. Our motivation resides on the fact that this could enable subsequent uniform approximations of analogous moments and their derivatives. We derive...

In this paper we are interested in investigating the effects of the threepart tariffs system on consumers’ behavior in the local fixed telephone service provided by the incumbent Telecommunications Company une in Medellín, which was authorized by the Telecommunications Regulatory Commission...

Despite the large body of firm-level analyses devoted to the impact of Information and Communication Technologies (ICT)-capital on productivity, a robust empirical evidence for developing countries is still needed. Starting from a commonly employed production function framework, the aim of this...

Foreign Direct Investment has become one of the major challenges for the countries who participated in international economy. It affects the host country by increasing its national income, labor productivity and employment. It also has some spillover effects, including technology transfer, new...
