This paper estimates a sequence of energy‐saving technology choices by Dutch glasshouse firms. The model allows for time‐constant, firm‐specific effects and serial correlation of errors and it is estimated on panel data over the period 1991–1995. The unobserved error sequences are simulated in the model in such a way that they are consistent with the observed choices. The results suggest that positive revenue shocks encourage adoption of new technologies. The choices also exhibit firm‐specific persistency over time. An increase of the price of energy encourages the adoption of a highly efficient energy‐saving technology. The probability of investing in energy‐saving technologies also decreases with capital invested in structures (e.g. double glazing of glasshouses) and increases with capital in energy installations. 相似文献

Intra-firm efficiencyinvolves computing a particular firm's efficiency degree overtime relative to the firm-specific production frontier. Inter-firmefficiency reveals a particular firm's performance over timerelative to the ``best practice frontier' among the set of comparablefirms. These efficiency measures are related by an inter-firmcatch-up component reflecting differences in technology acrossfirms. Those measures are estimated for Dutch pot-plant firmsusing the Generalized Maximum Entropy formalism. The empiricalresults suggest the inter-firm catch-up component is the majordeterminant of inter-firm efficiency. 相似文献

This paper uses a Mean-Variance utility function to build a dual model that simultaneously determines area allocation and production/input levels under output price uncertainty. Regularity conditions of the indirect utility function (convexity) and producers risk preferences are tested. The framework is applied to a rotating sample of Dutch arable farms. Dutch arable farmers are found to be risk averse, with the size of the risk premium given by 3 per cent of annual profit. A bootstrap resampling method shows that curvature conditions are rejected. Price elasticities are compared for an unrestricted model and for a model with curvature conditions being imposed. 相似文献

This study develops a microeconometric model of specialized dairy farms in the Moscow region using panel data over the period 1995–2001. The model is used to analyze the role of subsidies on profit as well as input and output allocation. Theoretical conditions for short‐term profit maximization are not rejected by the data. Differences between farms allow for a fixed‐effect specification. The dairy producers in the region demonstrate a low responsiveness to market signals, but technology change becomes important. Labor, land, and livestock had low shadow prices. Although subsidies have a distorting effect on the input–output mix, this study shows they relieve the credit constraints on dairy farms and have an important positive influence on farm profit. 相似文献

In corporate finance, the impact of capital structure on firm performance has been widely studied. This article extends the capital structure study to the situation in agriculture, explicitly addressing the difference between family farms and corporate firms. We use the Malmquist productivity growth index as a proxy for performance to study the impact of capital structure (debt) on farm performance. We compare the results with those from the traditional performance model that uses profitability (e.g., return on equity (ROE)) as performance measure. Using data from Dutch arable farms, results show that debt has no effect on ROE, whereas it has a positive effect on productivity growth. 相似文献

This article investigates trends in industrial concentration and its relationship with the price-cost margin in 54 subsectors of the Indonesian food and beverages sector in the period 1995 to 2006. This study uses firm-level survey data provided by the Indonesian Bureau of Central Statistics (BPS), classified at the five-digit International Standard Industrial Classification (ISIC) Level. The results show a significant increase in industrial concentration in 1995 to 1999, which coincided with the period of the economic crisis in Indonesia. After 1999, the industrial concentration exhibits a slightly decreasing long-term trend. Furthermore, the industrial concentration for all subsectors tends to converge to the same value in the long run. Additionally, results show that higher industrial concentration yields a higher price-cost margin. Finally, the introduction of the competition law in 1999 has slightly lowered industrial concentration and the price-cost margin. 相似文献

When designing effective voluntary vaccination strategies against animal disease epidemics, policy-makers need to take into account that different groups of farmers base their participation decisions on different considerations. Using the past Bluetongue virus serotype 8 epidemic of 2006–2009 in Europe as an example, this paper uses the Reasoned Action Approach to identify a set of attitudinal beliefs being the major drivers behind the intended decision to participate in voluntary vaccination. The results show that there is heterogeneity among farmers in these beliefs. In particular, perceived risk, which was captured by a risk attitude and a risk perception of the farmer, and personality traits are associated with variability in beliefs about vaccination against Bluetongue. The patterns found between perceived risk, personality traits and other farm and farmer characteristics were discussed in relation to the governance of animal health. 相似文献
