Growth determinants,intra-distribution mobility,and convergence of state-level agricultural productivity in the USA

Stochastic kernels and state-level data are used in this paper to investigate mobility and convergence of the agricultural Total Factor Productivity (TFP) in the U.S.A. and to determine the influence of certain growth-related factors on the shape of the equilibrium TFP distribution. According to the empirical results, increasing returns to scale, materials intensity, and regional differences are likely to increase the dispersion of the cross-section TFP distribution, while higher rates of catchingup work towards reducing it.

Multiple Job Holding,Skill Diversification,and Mobility

In this article, we investigate the interrelated dynamics of dual jobholding, human capital, occupational choice, and mobility, using a panel sample (1991–2005) of UK employees from the British Household Panel Survey. The evidence suggests that individuals may be using multiple jobholding as a conduit for obtaining new skills and expertise and as a stepping‐stone to new careers, also involving self‐employment. Individuals doing a different secondary job than their primary occupation are more likely to switch to a new primary job in the next year, and a job that is different than their current primary employment. The results show that there are human capital spillover effects between primary and secondary employment.     

Accounting earnings and gross domestic product

We document that aggregate accounting earnings growth is an incrementally significant leading indicator of growth in nominal Gross Domestic Product (GDP). Professional macro forecasters, however, do not fully incorporate the predictive content embedded in publicly available accounting earnings data. As a result, future nominal GDP growth forecast errors are predictable based on accounting earnings data that are available to professional macro forecasters in real time.     

The Theory-Practice Gap in Capital Budgeting: Evidence from the United Kingdom

We report the results of a survey of capital budgeting techniques used by United Kingdom firms. Where possible, the evidence is combined with data collected over a 22 year period to provide a basis for the discussion of causes of trends. We observe that there has been a substantial narrowing of the theory-practice gap in the use of project appraisal methods. The gap has also narrowed in other areas: the analysis of risk, inflation adjustment, capital budget preparation, WACC calculation and post-auditing. However, there are other elements of capital budgeting theory, e.g. probability and beta analysis which have been adopted by very few practising managers. We also discuss non-economic projects, capital rationing and hurdle rates.     

Quadratic Differential Demand Systems and the Retail Demand for Pork in Great Britain

The primary objective of this paper is to derive a general synthetic quadratic (rank 3) differential demand system which nests within it a range of testable differential demand models including the quadratic AIDS, CBS, Rotterdam and NBR systems. A model selection test procedure is also outlined. These differential systems are then applied and tested to analyse the monthly retail demand for cuts of pork in Great Britain over the period 1989–2000. The empirical results suggest that a quadratic differential AIDS model is most appropriate for the pork demand system studied, but that the need for inclusion of quadratic income/expenditure terms is not universal for every cut within the demand system. Quadratic expenditure effects were appropriate for pork chops and leg roasts, but log linear expenditure effects were adequate for bellies, shoulders and loin roasts. Roasting cuts were expenditure and own price elastic, with pork loins, chops and bellies all expenditure and own price inelastic.     

Constructing the true cost of living index from the Engel curves of the PIGLOG model

This paper investigates the properties of the Tornqvist index and shows how this can be used to construct a true cost of living index from a simple system of Engel curves. This allows the substitution bias inherent in a fixed weight index to be estimated using the maximum degree of commodity disaggregation available in the data. Furthermore the proposed index can be decomposed to show the impact of inflation on households with different expenditure levels and household chararacteristics. An empirical application of the method is given, using data on UK food expenditures.
