abstract t his paper explains bilateral trade patterns between south korea and thirteen opec member countries over the period 1980-2014 using a gravity model. the estimation results show that the gravity equation fits the data reasonably well. we confirmed the existence of long term relationships between the bilateral trade flows and the main components of gravity model - gdp, income (gdp per c...

This paper presents evidence on the contribution of public capital (infrastructure) to aggregate economic performance using panel data for the U.S. states from 1970 to 2005. Attempts to quantify the role of public or government capital in the production of aggregate output have been beset by thorny econometric issues since the early 1990s. We present estimates of the output elasticity of public...

Using a long panel of roll call voting data, I find that “flip-flopping” senators face significant electoral costs when changing positions. In models of electoral competition, as the costs to candidates changing position approach zero, the equilibrium prediction is the convergence of platforms. Such convergence is at odds with empirical observation. Using a dynamic, structural model of candidat...

A multiproduct cost function is estimated for English higher education institutions using a panel of data from recent years. The panel approach allows estimation by means of a random parameter stochastic frontier model which provides considerable new insights in that it allows the impact on costs of inter-institutional differences in the cost function itself to be distinguished from inter-insti...

generally, developing countries are not able to invest enough on r&d; therefore, they try to get benefit from knowledge spillover, as an external r&d.; this paper tries to investigate the impact of r&d; expenditures and imported intermediate goods, as a proxy for technology imports, on value added of iranian industries. to that end, we use a panel data set of iranian two-digit isic manufacturin...

Financial statements of nineteen mature banks have been patronized to examine the impact of macroeconomic indicators and bank-specific determinants on the NPLs ratio through Quantile and Panel Data regression approaches. The impact of macroeconomic indicators on credit risk is statistically estimated for banking network via two directions. First, different quantiles are econometrically calculat...

We examine the ability of the Expansionary Fiscal Contraction (EFC) hypothesis to explain the performance of of OECD economies during times of crisis. We ̄nd some limited evidence in its favour: if public consumption is reduced in response to a ̄scal crisis (as de ̄ned by a high level of debt), private consumption does seem to increase. However the size of the e®ect is smaller than that typicall...

this article is a comparative study of estimation power of artificial neural networks and autoregressive time series models in inflation forecasting. using 37 years iran’s inflation data, neural networks performs better on average for short horizons than autoregressive models. this study shows usefulness of early stopping technique in learning stage of neural networks for estimating time series...

This research examines whether technology transfer, research intensity, educational attainment and the ability to absorb foreign technology help explain cross-country differences in productivity growth. Our data comprise a panel of 55 countries including 23 OECD and 32 developing economies over the period 1970-2004. The results show that TFP growth in both OECD and developing countries is posit...
