Efektivitas Pasar Lelang Bahan Olah Karet dalam Koperasi Unit Desa

The auction market for crumb rubber is a business unit owned by KUD Berkat. The auction market was formed to obtain the highest price at the farmer level for the sale of crumb rubber. Therefore in this study, it is necessary to evaluate the effectiveness of the auction market for crumb rubber seen from the price, quality, volume, and the number of auction market players and to analyze farmers' perceptions of the effectiveness of the auction market from the auction market output, auction market flexibility, and whether there is tension between institutions in auction market with proportion test. Data collection uses secondary data and primary data obtained by interviewing respondents from weighting a Likert scale, and secondary data obtained from related institutions. The results showed that evaluation of effectiveness the auction market for crumb rubber seen from the price in line with the international market, the quality according to SNI standards and 98% of farmers had fulfilled the 60% KKK, the average of quantity (volume) of crumb rubber every farmer was in a low category, the number of farmers who participated auctions in the five years ago still increased. Farmers' perceptions of the auction market institution for crumb rubber based on the proportion test of more than 50% mean the auction market in KUD has a high level of effectiveness and is feasible to run.

Optimal Growth in Two-Sided Markets

We develop a theoretical model of optimal growth in two-sided markets. The model posits that market output (number of transactions) is a function of the stock of supply and demand. This market output is modeled using a homogeneous production function, which can have increasing or decreasing returns to scale. The supply and demand stock levels follow a growth model in which the rate of growth at each point in time is a function of both the surplus each side of the market receives and the attrition of supply and demand (supply and demand lifetimes). The surplus can be apportioned between the two sides of the market by changing the price paid to sellers and the price charged to buyers, which we assume the platform controls. Through these price levers, the platform can pay subsidies to one or both sides of the market. We investigate the behavior of optimal market growth, including the point at which the market becomes self-sustaining and the long-run optimal size of the market. We characterize the optimal balance between supply and demand as the market size grows and determine optimal subsidy policies that maximize discounted total profit. For the case of both increasing and decreasing returns without price constraints, we show the optimal policy is to grow using an impulse of subsidy spending (a subsidy shock) to move the market immediately to its optimal long-run size. This result is consistent with the race to growth observed in many two-sided markets like ride-sharing. This paper was accepted by Gabriel Weintraub, revenue management.

Integrated Assessment of Farming System Outputs: Lithuanian Case Study

Agriculture provides people with different market outputs. However, market outputs are not the only kind of output provided by agriculture: non-market outputs are produced jointly with the market ones in an agroecosystem. All the outputs produced by agriculture can be classified as the ecosystem services. The magnitude and levels of farming outputs depend on different technologies of production; i.e. different farming systems generate different outputs. Assessing the output of agriculture is quite simple in terms of the market value, but not so easy for non-market outputs. Moreover, evaluation of market and non-market outputs is usually performed separately. The objectives of this paper are to present an integrated evaluation framework for the outputs, marketable and non-marketable, associated with different farming systems. For the case study, we proposed the evaluation of the market and non-market output, associated with milk production in Lithuania, considering both organic and conventional production. In terms of the market evaluation, the results have shown that organic farming produced a value 1.24 times higher than conventional, while the valuation result associated with the non-market output is 83 time higher in organic than in conventional one. The study is the first attempt to develop a framework for integrated evaluation of farming outputs, taking into account market and non-market outputs and considering different types of farming systems.

STRUCTURAL CHANGES IN THE MILK PRODUCTION SECTOR AND FOOD SECURITY – THE CASE OF POLAND

The aim of the work was to find an answer to the question of how the changes in the milk production sector in Poland, following the marketization of the economy, influenced the country’s food security in the context of food self-sufficiency. The paper uses cow milk balances developed by the Central Statistical Office and data concerning the distribution of domestic milk production from the Institute of Agricultural and Food Economics National Research Institute. The study used a comparative analysis over time, indicators as well as descriptive and graphic methods. The indicators used concerned milk market output, food self-sufficiency and the milk balance structure. During the first few years of transformation, there was a sharp drop in domestic milk production. Since 2004, there has been, with minor exceptions, a systematic increase in production with a previous general fall in production volume. These processes were accompanied by changes resulting from the transformation of the economy in the milk production sector. These were associated with a drastic reduction, since 1990, of the number of farms involved in milk production and the decline in the number of dairy cows, albeit with a simultaneous increase in milk yield. The milk market output index increased. In 2015, resource in the milk balance returned to the level of 1991, i.e. over 14.5 bln liters. In 2017, this figure amounted to 15 bln liters. Domestic milk production is the main source of resource, though the volume of imports is significantly increasing. Despite dynamic growth of exports, milk is mainly used for domestic consumption. From 1990 onwards, Poland has significantly improved its self-sufficiency in milk production. Changes in milk production have significantly influenced food security in the country.

Peculiarities of accounting of reserves and unfinished production in the system of national accounts

The article has been devoted to the study of the problems of applying the information of financial statements of enterprises and organizations in the formation of fundamental macroeconomic indicators. The features of the methodology of the agreed accounting systems have been examined, the theoretical aspects of inventory accounting and unfinished production, when assessing the market output in the System of National Accounts, have been studied. The main macroeconomic indicators in International financial reporting standards (IFRS) and the System of National Accounts have been considered. The main components of the gross output and assumptions, on the basis of which the choice of the intermediate account format, have been adduced.

The Allocation of Talent and U.S. Economic Growth

In 1960, 94 percent of doctors and lawyers were white men. By 2010, the fraction was just 62 percent. Similar changes in other highly‐skilled occupations have occurred throughout the U.S. economy during the last 50 years. Given that the innate talent for these professions is unlikely to have changed differently across groups, the change in the occupational distribution since 1960 suggests that a substantial pool of innately talented women and black men in 1960 were not pursuing their comparative advantage. We examine the effect on aggregate productivity of the convergence in the occupational distribution between 1960 and 2010 through the prism of a Roy model. Across our various specifications, between 20% and 40% of growth in aggregate market output per person can be explained by the improved allocation of talent.

Macroeconomic costs of gender gaps in a model with entrepreneurship and household production

This paper examines the quantitative effects of gender gaps in entrepreneurship and workforce participation in an occupational choice model with a household sector and endogenous female labor supply. Gender gaps in workforce participation have a direct negative effect on market, while gender gaps in entrepreneurship affect negatively market output not only by reducing wages and labor force participation but also by reducing the average talent of entrepreneurs and aggregate productivity. We estimate the effects of these gender gaps for 37 European countries, as well as the United States, and find that gender gaps cause an average loss of 17.5% in market output and 13.2% in total output, which also includes household output. Interestingly, the total output loss would be similar (12%) in a model without household sector, since the market output loss is larger when the female labor supply is endogenous. Eastern Europe is the region with the lowest income fall due to gender gaps, while Southern Europe is the region with the largest fall. Northern Europe is the region with the largest productivity fall, which is due to the presence of high gender gaps in entrepreneurship.

Alternative representation of the deadweight loss triangle in oligopoly

Purpose The purpose of this paper is to provide an alternative way of calculating the deadweight loss triangle in oligopolistic markets which takes inefficient use of inputs into account. The author shows that the result of the approach coincides with the one that exists in the economics literature. However, the author explicitly accounts for the inefficient use of inputs. Design/methodology/approach The market supply curve that is extensively used for competitive markets has been reconsidered for the imperfectly competitive markets. The necessary condition for the efficient use of resources is investigated and a price level is derived at which the market output of oligopoly is produced efficiently. The degree of inefficient use of inputs is reported via the definitions of Input Inefficiency Measure (IIM) and the Ratio of Inefficient usage of Inputs to Total Deadweight Loss (RITD). Findings The author discovers that the area under the supply curve of the competitive market corresponds precisely to the minimum total costs of producing any given market output. To make this important finding operational in imperfectly competitive markets, the IIM reports the degree of distorted input allocation among firms with differentiated cost structures in producing a given equilibrium imperfectly competitive market output. In measuring the monopoly power, it is known that CRn or HHI market concentration indexes, which are calculated based on the market shares of firms regarding the demand side of the market, are widely used. The measures, which take into account of the distortions in input usage, and hence, the supply side may be considered as an additional index. For example, if the market demand were shared equally by two firms (no dominant firm with respect to the demand side), it is known that the leadership would still arise when the costs of firms differed as in the dominant firm model in favor of the lower cost producing firm. Research limitations/implications The author recommends some more theoretical research extensions of the approach suggested here to other oligopolistic markets like the Cournot-Nash, the Stackelberg and other models. In all cases, there is a need for additional work to find some measurable variables in practice in order to estimate the input inefficiency given by the two measures and differentiate it from the inefficiency of units of outputs that are not produced. Practical implications It may be interesting to decompose the various estimates of welfare losses due to monopoly power as a percentage of GNP that were discussed in the literature into two inefficiency components: units of outputs that are not produced and units of inputs that are misallocated among firms. Social implications The government officials might be interested in assessing the degree of loss of input usage by firms in addition to output loss in oligopolistic markets summarized by the two inefficiency indexes. Law economists may be inspired in discussing the issue of input inefficiency in the context of on antitrust policy. Originality/value The author emphasized that the area under the market supply curve minimized the aggregate cost of producing a given total market output in competitive markets. Having recognized the importance of this finding, the author tried to apply it to imperfectly competitive markets and especially to the calculation of deadweight loss in such markets. The author showed that the total social cost could be calculated by including the input inefficiency which can be defined as the extra cost to society arising from not using the most appropriate economic resource allocation among firms in addition to the usual deadweight loss triangle. Moreover, the author had to introduce some more new terms like the market supply curve allocation, the adjusted competitive price, efficiency gain and so on, as they were necessary along the course of the analysis.

Integrational links between agriculture and food industry in Podkarpacie

The paper presents factors influencing the integration of agriculture and food industry in the Podkarpackie voivodship. The status analysis of these dependencies in 2005 and 2013 was prepared on the basis of data obtained from surveys among agricultural producers. For the purpose of the analysis powiat was adopted as a research unit for spatial comparisons. The impact of the analysed factors on the integration of the food economy in the region was assessed. In the computation of integrational links intensity the value of contract production in the total value of market output of agricultural farm was considered. The presented results show that the development of the examined relationships is determined by, i.a.: percentage of agricultural farms producing mainly for market, share of agricultural land in the total area, stocking density of pigs per 100 ha of arable land and density of hard surface roads. As a result, it can be stated that the development of agri-food integration depends mainly on the profitability of agricultural production.
