We derive a framework for asymptotically valid inference in stable vector autoregressive (VAR) models with conditional heteroskedasticity of unknown form. We prove a joint central limit theorem for the VAR slope parameter and innovation covariance parameter estimators and address bootstrap inference as well. Our results are important for correct inference on VAR statistics that depend both on t...

abstract o ur basic aim in this paper concerns the question that if overusing the information technology by service and manufacturing firms can increase the total productivity resulting from this kind of technology regarding the iran's economic structure and conditions. for this purpose, we primarily evaluate the productivity resulting from the rate of firms' use of it for the differe...

In order to increase the fiber productivity in cotton, it is imperative genetically improve component traits and such effort can be quickened by use of molecular markers. Totally, seventy-four simple sequence repeat (SSR) markers that were previously shown linked fibre strength, boll weight, elongation used differentiate Gossypium hirsutum var. MCU5 TCH1218 among them two found polymorphic Thes...

In this paper we examine the interaction between the different modes of market access commitments in services (cross-border and establishment) market structure, and regulation. In this context, we focus on the impact of improved domestic market access for a foreign service provider on a domestic service market. We work with a model where the domestic industry is assumed to be imperfectly compet...

When cost is private information in the Brander{Spencer model, the home government is confronted by a decision of choosing between two policy options: a menu of policies and a uniform policy. The former induces separation and so reveals the cost information to the foreign competitors. The latter helps the weak ̄rm by concealing the cost information. The main result from this study is that polic...

It has become increasingly common to produce goods in a number of geographically dispersed stages linked by international trade. This tendency, known by names such as “production fragmentation”, “processing trade”, and “vertical specialization”, has important implications for the analysis of nontariff measures (NTMs) and trade facilitation. First, different types of NTMs or trade facilitation i...

This paper provides a theoretical and empirical analysis of public opinion towards free trade, investigating cleavages both between and within countries. We study the distributional effects of trade policy in a neoclassical economy with not just two, but many input factors in production. We demonstrate that the factor price changes induced by trade policy are negatively correlated with the fact...

A large share of world trade, especially among the OECD countries, is two-way trade within industries, so called intra-industry trade. Despite this, few attempts have been made to examine why countries export some products within industries, whereas they import others. We examine this issue, by means of regression analysis, by examining the shares of IIT that are vertical and horizontal and by ...

 In this paper, a version of the Vector Auto Regression (VAR) model has been used to investigate the interacted and dynamic effects between social capital and economic development in Iran during the period 1987-2006. To this purpose, variables of human capital, health and income distribution have been considered as the proxies of economic development. In addition, the volume of risky bank chequ...
