In this paper, we investigate the class of quasi-homogeneous production models, obtaining the classification of such models with constant elasticity with respect to an input as well as with respect to all inputs. Moreover, we prove that a quasi-homogeneous production function f satisfies the proportional marginal rate of substitution property if and only f reduces to some symmetric production functions.

We completely classify homogeneous production functions with proportional marginal rate of substitution and with constant elasticity of labor and capital, respectively. These classifications generalize some recent results of C. A. Ioan and G. Ioan (2011) concerning the sum production function.

In this paper, we give a simple geometric characterization of homogeneous production functions, by studying geometric properties of their associated graph hypersurfaces. For a homogeneous production function, we prove that its corresponding hypersurface with constant sectional curvature must be flat. Therefore, by combining this with Chen and V?lcu?s recent results, we obtain a new geometric characterization of homogeneous production functions having constant return to scale.

Almost all economic theories presuppose a production function, either on the firm level or the aggregate level. In this sense the production function is one of the key concepts of mainstream neoclassical theories. There is a very important class of production functions that are often analyzed in both microeconomics and macroeonomics; namely, $h$-homogeneous production functions. This class of production functions includes two important production functions; namely, the generalized Cobb-Douglas production functions and ACMS production functions. It was proved in 2010 by L. Losonczi \cite{L} that twice differentiable two-inputs $h$-homogeneous production functions with constant elasticity of substitution (CES) property are Cobb-Douglas' and ACMS production functions. Lozonczi also pointed out in \cite{L} that his proof does not work for production functions of $n$-inputs with $n>2$

The article is devoted to the study of inverse problems of identifying two-factor production functions from given marginal rate of technical substitution. The analytical forms of twofactor production functions with given linear-fractionalmarginal rate of technical substitution of labor by capital. Classes of two-factor production functions that correspond to given (constant, linear, linear-fractional, exponential, etc.) marginal rate of technical substitution areindicated. The obtained results can be applied in modeling of production processes.

Abstract In this paper, we investigate the relationship between economic output, labour and capital in the Visegrád Four, Austria and Germany. The main objective is to determine the type of technological progress in these countries over time, specifically in the period 1995-2015. The Sato production functions (a special case of the linearly homogeneous production function) for all the aforementioned countries are estimated using linear and nonlinear techniques. In addition to the original Sato production function, we propose modifying it in using a time variable, which allows us to analyse the development of productivity over time. Based on the NLS estimates of this modification, we create isoquant maps and calculate the value of the marginal rate of technical substitution of labour for capital to identify the nature of technological progress typical for each country. We also compare the properties of both the OLS and NLS estimates. The results are quite specific to individual countries, but there is some room for generalization.

Water and fertilizer among the production factors are the elements that most restrict the production of cashew. The precise amount of these factors is essential to the success of the crop yield. This research aimed to determine the best factor-product ratio and analyze technical and economic indicators, of productivity of the cashew clone BRS 189 (Anacardium occidentale) to production factors water and potassium. The experiment was conducted from May 2009 to December 2009 in an experimental area of 56.0 m x 112.0 m in the irrigated Curu - Pentecoste, located in the municipality of Pentecoste, Ceará, Brazil. Production factors water (W) and potassium (K) were the independent variables and productivity (Y), the dependent variable. Ten statistical models that have proven satisfactory for obtaining production function were tested. The marginal rate of substitution was obtained through the ratio of the potassium marginal physical product and the water marginal physical product. The most suited model to the conditions of the experiment was the quadratic polynomial without intercept and interaction. Considering that the price of the water was 0.10 R$ mm -1, the price of the potassium 2.19 R$ kg -1 and the price of the cashew 0.60 R$ kg-1, the amounts of water and K2O to obtain the maximum net income were 6,349.1 L plant-1 of water and 128.7 g plant -1year, -1 respectively. Substituting the values obtained in the production function, the maximum net income was achieved with a yield of 7,496.8 kg ha-1 of cashew.

Abstract Background Research has highlighted that satisfaction in health and social support are key areas of life affecting individual’s wellbeing. Many social and public health initiatives use these two intervention mechanisms to improve individual’s wellbeing. For the purpose of cost-benefit assessment, there has been growing interest in expressing these intervention effects in economic terms. However, only a handful of studies have ever estimated these effects in economic terms, and none of which examined in a Chinese context. The aim of this study is to extend this line of valuation work to estimate the implicit willingness-to-pays on the effects of improving individuals’ self-rated health status (SRH) and social support (SS) on their life satisfaction in the Chinese population. Methods Using individual’s life satisfaction data from a two-wave representative panel survey in Hong Kong (n = 1,109), this study first conducted a cross-lagged analysis with structural equation modelling technique to examine the causal effects of SRH and SS on life satisfaction, while simultaneously adjusting their reverse causal influences. The use of this cross-lagged approach was the effort to minimising the endogeneity problem. Then, substituting the respective estimates to the formulae of compensating surplus, the marginal rate of substitution of SRH and SS with respect to individual’s equivalised monthly household were estimated and were then expressed as the willingness-to-pays on the effect of improving individuals’ SRH and SS on their life satisfaction. Results The cross-lagged analysis ascertained the casual effects of SRH (β = 0.078, 95%CI: 0.020, 0.151) and SS on individuals’ satisfaction with life. The sample’s marginal rate of substitution of SRH and SS were found to be 1.28 (95%CI: 0.43, 2.15) and 1.36 (95%CI: 0.23, 2.49) respectively. Translating into the concept of compensating surplus, the implicit monetary values of improving the sample’s SRH from “poor health” to “excellent health” and their SS from “little support” to “a lot of support” are equivalent to an increase in their equivalised monthly household income by HK$56,000 and HK$39,400 respectively. Conclusions This study has implications for the cost-benefit assessment in wellbeing initiatives for the Chinese population.
