The U.S. export share in the world peanut market has decreased due to heavy competition. In this paper, the Latin American peanut industry is modeled using seemingly unrelated regression (SUR). Based on these estimations, a scenario analysis was conducted. The results show that the Latin American demand is not affected dramatically by either domestic or world price shocks. The effects of price changes on net trade are noticeable. However, the world price does not significantly affect the Latin American peanut supply. The results imply that Latin American peanut farmers are more sensitive to changes in domestic prices than world price changes.

This study aims (1) to assess the factors of production and their effects on soybean production, and to investigate the ability of input levels, such as area and others to explain the response of production; and (2). assess the response of farmer supply to input prices, receipt of gross expectations, from related variables, and other exogenous variables. This research was conducted in 2017 in East Tanjab Regency. The method of analysis in its application is sorted based on the research objectives namely the Empirical Model of the Response Response Function. From the research, the results obtained from the soybean supply response model are strongly influenced by many factors. Among internal and external factors such as soybean prices, use of inputs, and seasons, which are quite relevant where soybean production increases because soybean prices increase. It also added that soybean production decreases when the input variables used are not in accordance with the provisions. As expected it was also found that the harvested area was also a significant determinant of crops. Furthermore it was found that soybean production increased during the rainy season. This finding is consistent with the fact that water availability is an important factor for soybean plants. The analysis also explained that soybean farmers in tidal land in the study area responded to the change in the use of efficient inputs. Supply of output is a response to soybean production. On input requests, many are sensitive to the use of labor, maintenance / harvesting labor. The elasticity of production obtained complements the part of the data base needed to evaluate the policy implications of using alternative inputs from soybean supply and input demand.

<p>Bawang merah merupakan salah satu komoditas sayuran yang mempunyai peran strategis bagi perekonomian Indonesia. Untuk meningkatkan produksi bawang merah, petani menggunakan beberapa input produksi. Perubahan harga bawang merah akan berdampak pada penawaran output dan permintaan input. Penelitian bertujuan untuk mengetahui pengaruh perubahan harga output dan harga input terhadap penawaran output dan permintaan input usahatani bawang merah di Kabupaten Demak, Jawa Tengah. Penelitian dilaksanakan di Desa Raji, Kecamatan Demak, Kabupaten Demak pada bulan September – Desember 2016. Penelitian menggunakan data primer yang dikumpulkan melalui metode survey terhadap 30 responden. Data dianalisis dalam bentuk pangsa permintaan input dengan metode Seemingly Unrelated Regression (SUR). Hasil penelitian menunjukkan bahwa penawaran bawang merah elastis terhadap perubahan harga bawang merah dan harga umbi benih, namun kurang elastis terhadap perubahan upah tenaga kerja, serta tidak elastis terhadap perubahan harga pupuk. Permintaan input (umbi benih, pupuk, dan tenaga kerja) bersifat elastis terhadap harga masing-masing input tersebut, dan sebagian besar bersifat inelastis terhadap harga input lainnya. Oleh karena itu untuk meningkatkan penawaran bawang merah, pemerintah seyogyanya mampu menjaga stabilisasi harga bawang merah dan mendorong menggunakan biji bawang merah (true seed shallot) sebagai alternatif untuk mengurangi pemakaian benih umbi bawang merah.</p><p><strong>Keywords</strong></p><p>Bawang merah; Perubahan harga; Penawaran output; Permintaan input</p><p><strong>Abstract</strong></p><p>Shallot is one of the vegetable crops that have a strategic role for the Indonesian economy. To increase the production of shallot, the farmers using several of input production. Changes of shallot would have an impact to output supply and input demand. This study aimed to determine the effect of changes in input and output prices to output supply and input demand of shallot farming. The study was conducted in Raji Village, Demak Subdistrict, Demak District in September - December 2016.  Primary data was collected through survey method by interviewing 30 respondents. The data was analyzed in the form of input demand share by Seemingly Unrelated Regression (SUR) method.  The results showed that supply of shallot is elastic to the price changes of shallot and price of seed bulbs, but less elastic to changes in labor wages and inelastic to changes in fertilizer prices. Demand for production input is elastic to the price of each input, and are largely inelastic with respect to other input prices. Therefore, to increase the shallot supply, the Government should be able to maintain the stabilization of shallot prices and encourage the use of true seed shallot as an alternative to reduce the use of shallot seeds.</p>

Vehicle type purchase intentions are interesting from a marketing point of view, because car manufacturers are competing to attract potential buyers. Furthermore, from the point of view of transport planners as well as the government, there are environmental concerns. This study focused on students’ intention to purchase different types of vehicles. The study obtained a sample of 1,229 students from seven countries, to understand cultural differences in preferences. The dependent variables were intention to buy cars in different categories, including hybrid and electric cars. The aim was to explain intentions with three categories of explanatory variables: psychological aspects, sociodemographics, and site-specific dummy variables. To account for correlation between the dependent variables, the analysis used seemingly unrelated regression. The study found that attitudinal factors are significant, particularly for the intention to buy more environmentally friendly types of vehicles; the paper discusses policy implications. The study observed the importance of the symbolic-affective value of a car in explaining car type preferences, as well as the importance of awareness of the negative effects cars might have on the environment and society. It is suggested that these findings can be used to promote more environmentally friendly cars.

Using Data

The article examines the link between workplace disability (WD) and workplace job satisfaction (JS) using data from WERS2011. Controlling for a rich set of workplace characteristics including organisational culture, the study finds a significant negative relationship between JS and the share of disabled respondents within workplaces. Notably, Seemingly Unrelated Regression (SUR)-based analysis distinguishing between disabled and non-disabled respondents reveals that the negative relationship found is specific to non-disabled respondents. Moreover, disability equality policies are found to be significantly positively related with disabled respondents’ JS while they are negatively related with the JS of their non-disabled counterparts. The article ponders if there is a co-worker aspect to the WD–JS link and whether HR policies may need to take heed of co-worker dynamics in this respect.
