Price Rigidity and Industrial Concentration: Evidence from the Indonesian Food and Beverages Industry 下载免费PDF全文
This paper investigates the relationship between industrial concentration and price rigidity in the Indonesian food and beverages industry. A Cournot model of firm behavior is used in which prices adjust according to a partial adjustment mechanism. The model is applied to panel data of the Indonesian food and beverages industry over the period 1995–2006. The results suggest that industrial concentration has a positive effect on percentage price changes. Furthermore, the speed of price adjustment is higher when the per unit cost of production rises. 相似文献

We provide explorative insights on how farms which manage strong and successful growth affect farms in their neighbourhoods through spatial competition for land. The study is based on an exploratory analysis of repeated framed experiments within the business game FarmAgriPoliS (Appel & Balmann, Ecological Complexity, 40, 2019). In particular, we analyse the spatial influences of different behavioural clusters of farm managers. Our analysis finds that farms which manage strong growth substantially affect the development of farms in a spatial neighbourhood of some 10 km. Although the influence on the neighbourhood decreases with distance, the functional correlations of farm growth as well as exits are neither linear nor exponential, but eventually rather wave-like. We further discuss the spatial interdependence of farms and the related overlaps of the predator–prey phenomenon with the phenomena of farms' path dependency and agricultural structural change. We conclude that along with farmers' strategies and their abilities, the characteristics of their neighbours and the distances between neighbouring farms also determine who is ‘predator’ and who is ‘prey’. 相似文献

This article presents an overview of the development of Russian agricultural enterprises in 1990–2001. The multi‐layered structure of agriculture represented by different categories of non‐commercial and commercial producers requires a clear distinction of policies with respect to their targets and end results. The agricultural enterprises maintained their leading role in marketed agricultural production and represent the main focus group among the agricultural producers for policy makers. The article reviews organisational and structural changes to these enterprises in the period studied, and their economic and financial performance. It also examines current policies for resolving the problems in agriculture. 相似文献

On the 3rd of May there begins in Nairobi the fourth UNCTAD Conference. It is in a way like the fourth landmark on a way that has taken twelve years so far to travel; a good opportunity therefore to review critically to what extent the claims made on behalf of these conferences are justified, what success they have achieved and what the prospects are of their achieving further successes in the future. 相似文献

The effectiveness of imperfect pollution control instruments is examined for a diffuse source, multi-contaminant problem in which the transport coefficients for sediment-bound residuals are endogenous. Similar evaluations fix the percentage of sediment deposited and optimize either for a single firm managing the whole watershed or on a firm by firm basis. This study shows that ignoring the dependence of the transport coefficients on intervening land uses creates a positive externality. The filtering potential of activities conducted by firms close to the receptor permits firms further away to undertake more profitable but erosive practices. Optimizing management choices, and consequently endogenizing the transport coefficients, for all firms simultaneously removes the externality. An empirical application combines hydrological simulation models with an economic optimization model for nutrient pollution of surface and ground water within an agricultural watershed. Although firms are homogeneous in abatement costs, differences in spatial location leave uniform instruments unable to achieve the water quality goal efficiently. An ambient tax/subsidy scheme can achieve the water quality goal efficiently but the informational requirements will be excessive in most situations where the transport mechanisms for residuals are dependent upon the practices of independent decision making units. 相似文献

This paper develops a short-run microeconomic simulation model of the Dutch glasshouse industry in order to investigate the relation between technical efficiency and marginal abatement costs of CO2 emission. The model is also used to determine the effects of an emission tax and systems of tradable and non-tradable quota for groups of firms with different rates of technical efficiency. The results show that marginal abatement costs are very responsive to changes in technical efficiency. Furthermore, it is found that firms with a low technical efficiency are faced with a higher profit reduction under different abatement policies than firms with a high technical efficiency. 相似文献
