A new panel data test for Granger causality is presented that can be applied to panels with more time series observations than cross-sections. Inconsistency in these models with lagged dependent variables and fixed effects is avoided by differencing and pooling the data. The joint significance...

This chapter extends the work of the previous chapters by fitting a long run profit function to investigate the sources of output growth in South African agriculture. In the long run, all the conventional inputs are treated as variable, but the technology-related variables are fixed because they...

This paper briefly presents the results of a total factor productivity (TFP) study of South African commercial agriculture, for 1947-1997, and illustrates some potential pitfalls in rate of return to research (ROR) calculations. The lag between R&D and TFP is analyzed and found to be only 9...

An error correction model (ECM) of induced innovation, based on the two-stage CES production function allows direct tests of the inducement hypothesis, which are applied to U.S. data for 1880-1990. The time series properties of the variables include a structural break in 1920, cointegration is...

Subsidised energy prices in pre-transition Hungary had led to excessive energy intensity in the agricultural sector. Transition has resulted in steep input price increases. In this study, Allen and Morishima elasticities of substitution are estimated to study the effects of these price changes...

Purpose - The purpose of this paper is to use the DuPont expansion to examine those factors underlying differences in (rates of) return on different crop portfolios over space (ten regions) and time (1960-2004). The paper also estimates the impact of government payments on farmland values...

We build up from the plant level an “aggregate(d)” Solow residual by estimating every U.S. manufacturing plant's contribution to the change in aggregate final demand between 1976 and 1996. Our framework uses the Petrin and Levinsohn (2010) definition of aggregate productivity growth, which...

Regional estimates of direct cost (DC) are commonly used to measure the economic damages of sea level rise. Such estimates suffer from three limitations:(i) values of threatened endowments are not well known, (ii) loss of endowments does not affect consumer prices, and (iii) international trade...

Hotter countries are poorer on average. This paper attempts to separate the historical and contemporaneous components of this income-temperature relationship. Following ideas by Acemoglu et al. (Am Econ Rev 91(5):1369-1401, 2001), we use colonial mortality data to account for the historical role...
