Offering a unifying theoretical perspective not readily available in any other text, this innovative guide to econometrics uses simple geometrical arguments to develop students' intuitive understanding of basic and advanced topics, emphasizing throughout the practical applications of modern theory and nonlinear techniques of estimation. One theme of the text is the use of artificial regressions for estimation, reference, and specification testing of nonlinear models, including diagnostic tests for parameter constancy, serial correlation, heteroscedasticity, and other types of mis-specification. Explaining how estimates can be obtained and tests can be carried out, the authors go beyond a mere algebraic description to one that can be easily translated into the commands of a standard econometric software package. Covering an unprecedented range of problems with a consistent emphasis on those that arise in applied work, this accessible and coherent guide to the most vital topics in econometrics today is indispensable for advanced students of econometrics and students of statistics interested in regression and related topics. It will also suit practising econometricians who want to update their skills. Flexibly designed to accommodate a variety of course levels, it offers both complete coverage of the basic material and separate chapters on areas of specialized interest.

The theory of the growth of the firm

Determinants of economic growth: A cross-country empirical study.

The economic development and growth literature contains extensive discussions on relationships between exports and economic growth. One debate centres on whether countries should promote the export sector to obtain economic growth. An abundant empirical literature on this export-led growth (ELG) hypothesis has followed. We aim to contribute to this literature in two ways. In this paper, part 1, we provide a comprehensive survey of more than 150 export-growth applied papers. We describe the changes that have occurred, over the last two decades, in the methodologies used empirically to examine for relationships between exports and economic growth, and we provide information on the current findings.The last decade has seen an abundance of time series studies that focus on examining for causality via exclusions restrictions tests, impulse response function analysis and forecast error variance decompositions. Our second contribution is to examine some of these time series methods. We show, in part 2, that ELG ...

Export-led growth: a survey of the empirical literature and some non-causality results. Part 1

Applying programming techniques to detailed data for 406 rice farms in 21 villages, for 1997, produces inefficiency measures, which differ substantially from the results of simple yield and unit cost measures. For the Boro (dry) season, mean technical efficiency was efficiency was 56.2 per cent and 69.4 per cent, allocative efficiency was 81.3 per cent, cost efficiency was 56.2 per cent and scale efficiency 94.9 per cent. The Aman (wet) season results are similar, but a few points lower. Allocative inefficiency is due to overuse of labour, suggesting population pressure, and of fertiliser, where recommended rates may warrant revision. Second-stage regressions show that large families are more inefficient, whereas farmers with better access to input markets, and those who do less off-farm work, tend to be more efficient. The information on the sources of inter-farm performance differentials could be used by the extension agents to help inefficient farmers. There is little excuse for such sub-optimal use of survey data, which are often collected at substantial costs.

Technical, Allocative, Cost and Scale Efficiencies in Bangladesh Rice Cultivation: A Non‐parametric Approach

Government size, factor accumulation, and economic growth: evidence from OECD countries

Production frontiers are estimated from survey data from a village in Bangladesh to examine the technical efficiency of farmers in the cultivation of traditional and high‐yielding‐variety (HYV) rice. In spite of much higher yields, HYV cultivation displays lower technical efficiency and much greater variability in efficiency. Also, efficiency is not independent of household endowments in that small farmers, and/or those with the least education and growing experience, are least efficient. Policies that promoted education and provided smaller farmers with greater access to public services would promote efficiency and equity, and help reduce HYV yield variability.

An empirical study of the patterns and sources of technical inefficiency in traditional and HYV rice cultivation in Bangladesh

This study attempts to examine empirically the implications of the degree of openness for total and individual factor productivity growth in a group of 19 OECD countries over the last three decades. The study combines both time series and cross-sectional data. The model employed is a generalization of the commonly used, growth-accounting model based on the concept of an aggregate production function in which the rate of economic growth is a function of capital and labour accumulation and total factor productivity. It is explicitly assumed that total factor productivity depends, in turn, upon the rate of export expansion. The model is then estimated using the random coefficients approach. While results generally indicate that the relative importance of trade openness on economic growth varies significantly across countries, they also indicate that the role of capital and labour accumulation in fostering economic growth varies with the degree of openness, cross-sectionally as well as across time.

A varying-coefficients model of export expansion, factor accumulation and economic growth: Evidence from cross-country, time series data

This paper extends the Feldstein-Horioka (1980), Feldstein (1983) and subsequent studies on the degree of capital mobility, by adopting a random coefficients model. This approach is more general in that it permits inter-country variations in the degree of capital mobility to arise due to the differences in size as well as in other institutional or structural characteristics. In addition, it is a refinement of stochastic laws as defined by Pratt and Schlaifer (1984, 1988). Our results point to significant inter-country differences in the degree of capital mobility, thereby lending support to the random coefficients approach. In particular, our results indicate that, on average, the degree of capital mobility is much higher than implied by fixed coefficients approach. Finally, country size itself does not appear to bear a systematic relationship with the degree of capital mobility as suggested by Murphy (1984).
