The Impact

<strong>English</strong><br />Central Java Province is one of sugarcane producing centers in Indonesia and Pati is one of sugarcane producing regencies in the province. A total of 5,905 households in Pati regency conduct sugarcane farming as their primary income source. However, sugarcane farmers deal withlimited capital to adopt productivity improving technologies. This study aimed to analyze factors influencing economic decisions of sugarcane farmers in allocating working hours, production, and household’s expenditure, as well as to analyze the impact of changes in input prices, output price, credit, and sugar level on sugarcane farmer household’s welfare in Central Java. Simultaneous equation models consisting of 21 structural equations and 22 identity equations were estimated using Two-Stage Least Squares (2SLS) method. The results showed that an increase in credit, sugar price, and sugar level could compensate increases in fertilizer price and labor wage and had positive impact on farmers’ welfare. Increases in fertilizer price and labor wage could be compensated through credit, sugar price, and sugar level enhancement. It is necessary that the Government increases sugar price and ensures farmers’ access to credit. It aims to encourage farmers to adopt technology through replanting (ratoon replacement) to improve sugarcane productivity and farmers’ welfare.<br /><br /><br /><strong>Indonesian</strong><br />Jawa Tengah merupakan salah satu sentra produksi tebu di Indonesia. Salah satu kabupaten sentra produksi tebu di Jawa Tengah adalah Pati. Sebanyak 5.905 rumah tangga petani tebu di Kabupaten Pati memiliki usaha tani tebu sebagai sumber pendapatan utama. Rumah tangga petani tebu dihadapkan pada masalah keterbatasan modal sehingga kemampuan adopsi teknologi rendah dan budi daya tidak optimal. Kondisi ini berdampak pada rendahnya produktivitas dan pendapatan rumah tangga. Penelitian ini bertujuan untuk menganalisis faktor-faktor yang memengaruhi keputusan ekonomi rumah tangga petani tebu dalam alokasi curahan kerja, produksi, dan pengeluaran rumah tangga, serta dampak perubahan harga input, harga ouptut, kredit, dan rendemen terhadap kesejahteraan rumah tangga petani tebu. Penelitian menggunakan data cross section dengan jumlah sampel sebanyak 56 rumah tangga petani tebu. Model ekonomi rumah tangga petani dibangun sebagai sistem persamaan simultan yang terdiri dari 21 persamaan struktural dan 22 persamaan identitas, lalu diestimasi menggunakan metode Two Stage Least Squares (2SLS). Hasil penelitian menunjukkan bahwa kebijakan peningkatan harga gula, jumlah kredit, dan rendemen gula berdampak positif terhadap kesejahteraan rumah tangga petani. Peningkatan harga pupuk dan upah tenaga kerja luar keluarga mampu dikompensasi dengan peningkatan jumlah kredit, harga gula, dan rendemen gula. Pemerintah sebaiknya meningkatkan harga patokan petani dan juga memperbesar jumlah kredit yang dapat diakses petani untuk mendorong adopsi teknologi dengan melakukan peremajaan tanaman (bongkar ratoon) yang bertujuan untuk meningkatkan produktivitas dan kesejahteraan rumah tangga.

The article is devoted to the estimation of econometric models of the Latvian economy. The Klein's simplified macroeconomic model of the Latvian economy is discussed. The endogenous variables are consumption, net investment, gross domestic product (excluding net exports and additions to reserves). An exogenous variable is the government spending. The model is just-identified, and Two-stage least squares (2SLS) method provides consistent estimates of the parameters of a structural equation. The modified Keynеsian model was also considered, where the lagged variable - gross domestic product of the previos period is presented. It is proved that the model is over-identified, and the Two-stage least squares (2SLS) method provides estimates of the parameters of a structural equation. We have estimated the models with annual time-series data of the Latvia economy for the years 1995 through 2011 (at basic prices in 2000).

The Impact

<strong>English</strong><br />Indonesian government has applied cigarette excise tax policy on clove cigarette which impacts on the rise of cigarette price and cigarette production. Because of tobacco and clove demand are derived demand of cigarette supply, so the change on cigarette production impacts on demand of cigarettes input (tobacco and clove) and it eventually impact on the price of these commodities. The rise of cigarette excise not only impacts on economic surplus of producer and consumer of cigarettes, but also on tobacco and clove farmers. Clove cigarette encompasses hand-rolled clove cigarettes (SKT), machine-rolled clove cigarettes (SKM) and klobot cigarettes (SKB). The aim of this research was to analyze the impact of the rise of cigarette excise tax policy toward economic surplus distribution among the economic agents on Indonesian cigarette industries. This research accomodated the data series of 1990-2016 with simultaneous equation system which consisting of 36 structural equations and 25 identity equations. This model was estimated by using 2 SLS (Two-Staged Least Squares) method. The results showed that cigarette excise tax impacted on the rise of government revenue and total economic surplus negatively. The rise of excise tax impacted on negative surplus of cigarette producer decreased, negative surplus of cigarette consumer increased, and farmer surplus decreased (negative). In order to keep positive economic surplus of the farmer, the rise of SKT cigarette tax maximum should be constituted no more than 5,8%. To anticipate the loss of farmer surplus and the decrease of tobacco and clove demand ini the future, the government can use the tax revenue to develop alternative crops besides tobacco such as vegetables, intensification of tobacco as import subtitution and develop diversification of clove products for essential oil, preservatives and others.<br /><br /><br /><strong>Indonesian</strong><br />Pemerintah Indonesia telah menerapkan kenaikan tarif cukai rokok kretek yang berdampak pada kenaikan harga rokok dan produksi rokok. Oleh karena permintaan tembakau dan cengkeh merupakan permintaan turunan dari penawaran rokok, maka perubahan produksi rokok akan berdampak pada permintaan input (tembakau dan cengkeh) dan berdampak pada harga kedua komoditas tersebut. Kenaikan cukai tidak hanya berdampak pada surplus ekonomi produsen dan konsumen rokok, tetapi juga petani tembakau dan cengkeh. Industri sigaret kretek meliputi sigaret kretek tangan (SKT), sigaret kretek mesin (SKM) dan rokok klobot (SKB). Tujuan penelitian ini adalah untuk menganalisis dampak kenaikan cukai rokok terhadap distribusi surplus ekonomi di antara pelaku ekonomi pada industri rokok di Indonesia. Penelitian ini menggunakan data deret waktu tahun 1990-2016 dengan sistem persamaan simultan yang terdiri dari 36 persamaan struktural dan 25 persamaan identitas, yang diestimasi menggunakan metode 2SLS (<em>Two-Staged Least Squares</em>). Hasil penelitian menunjukkan adanya tarif cukai rokok akan menambah penerimaan pemerintah namun berdampak negatif terhadap total surplus ekonomi. Kenaikan cukai rokok berdampak pada negatif surplus produsen rokok makin menurun, negatif surplus konsumen rokok makin meningkat dan surplus petani menjadi turun (negatif). Agar surplus ekonomi petani tetap positif, maka kenaikan tarif cukai khususnya SKT ditetapkan tidak lebih dari 5,8%. Pemerintah dapat memanfaatkan sebagian penerimaan cukai rokok untuk melakukan upaya pengembangkan alternatif tanaman lain selain tembakau seperti sayuran, intensifikasi tanaman tembakau subtitusi impor dan melakukan diversifikasi produk cengkeh sebagai minyak esensial, pengawet dan lainnya untuk mengatasi kerugian petani dan mengantisipasi turunnya permintaan tembakau dan cengkeh pada masa depan.

Farming Households

Unreliable access to a sufficient quantity of nutritious food is a major cause of undernourishment and malnutrition and may lead to reduced worker capacity and low productivity in developing countries. This study examines the impact of micronutrient intake on the labour productivity of rice-producing households in Thailand in 2011. A semi-log wage equation and Cobb–Douglas production function are estimated using two-stage least squares and non-linear two-stage least squares methods, respectively. The results show that higher intakes of calcium, vitamin A and iron increase household earnings and farm output. However, calorie intake only contributes to a higher farm output. Enhancing micronutrient consumption is an investment for improving productivity.

The Impact

Causal mediation analysis aims to estimate natural direct and natural indirect effects under clearly specified assumptions. Traditional mediation analysis based on Ordinary Least Squares assumes an absence of unmeasured causes to the putative mediator and outcome. When these assumptions cannot be justified, instrumental variable estimators can be used in order to produce an asymptotically unbiased estimator of the mediator-outcome link, commonly referred to as a Two-Stage Least Squares estimator. Such bias removal, however, comes at the cost of variance inflation. A Semi-Parametric Stein-Like estimator has been proposed in the literature that strikes a natural trade-off between the unbiasedness of the Two-Stage Least Squares procedure and the relatively small variance of the Ordinary Least Squares estimator. The Semi-Parametric Stein-Like estimator has the advantage of allowing for a direct estimation of its shrinkage parameter. In this paper, we demonstrate how this Stein-like estimator can be implemented in the context of the estimation of natural direct and natural indirect effects of treatments in randomized controlled trials. The performance of the competing methods is studied in a simulation study, in which both the strength of hidden confounding and the strength of the instruments are independently varied. These considerations are motivated by a trial in mental health, evaluating the impact of a primary care-based intervention to reduce depression in the elderly.

Pemerintah Singapura telah melakukan beragam kebijakan pengendalian tembakau (tobacco control) untuk menekan jumlah perokok. Singapura termasuk salah satu negara di dunia yang menerapkan regulasi ketat dalam pengendalian produk tembakau. Penelitian ini bertujuan untuk memperkirakan dampak penerapan kebijakan kemasan rokok Singapura terhadap ekspor rokok Indonesia. Kebijakan tersebut diasumsikan memiliki dampak sebagaimana kebijakan pengendalian konsumsi tembakau non-harga pada umumnya meskipun kebijakan tersebut belum diimplementasikan. Metode yang digunakan berupa analisis deskriptif yang dilengkapi dengan analisis ekonometri menggunakan Two-Stage Least Squares (2SLS) dengan sampel Triwulan III-2006 hingga Triwulan IV-2014. Hasil analisis menunjukkan bahwa ekspor rokok Indonesia lebih dipengaruhi oleh re-ekspor Singapura dibandingkan dengan konsumsi domestiknya. Selain itu, kebijakan pengendalian tembakau non-harga secara statistik tidak berpengaruh terhadap konsumsi rokok di Singapura. Oleh sebab itu, Indonesia tidak perlu khawatir dengan rencana kebijakan kemasan rokok yang akan diterapkan. Pemerintah Indonesia harus aktif melakukan negosiasi apabila Singapura benar-benar menerapkan kebijakan kemasan rokok dalam rangka mendapatkan kompensasi perdagangan atas kebijakan tersebut. The government of Singapore has implemented various tobacco control policies to reduce the number of smoker. Singapore is one of the countries in the world that implemented a tight regulation to control tobacco products. This study aims to estimate the potential impacts of Singapore’s cigarette plain packaging policy on the Indonesian cigarettes exports. As this policy is not yet implemented, it is assumed that the policy will have the same impacts as the common tobacco control policy, especially for the non-price policy. The study used descriptive analysis supported by econometrics analysis using Two-Stage Least Squares method (2SLS) using quarterly data from III-2006 to IV-2014. The results showed that the Indonesian cigarettes export is much more influenced by the Singapore’s re-exports rather than by the domestic consumption. Moreover, the non-price tobacco control policies do not have statistically significant effect on the cigarette consumption in Singapore. Therefore, Indonesia should not be worried about the possible implementation of the plain packaging policy. Indonesian government must actively negotiate if Singapore finally implements the plain packaging policy  to get a compensation trade from this policy.

The Impact

Based on the panel data of 277 cities between 2003 and 2017 and a unique city-level dataset of green patent applications, this study employs the difference-in-differences (DID) method to evaluate the effect of China’s carbon emission trading scheme (ETS) pilots on urban green innovation. The findings indicate that China’s ETS pilots have a positive impact on urban green innovation, and that impact is more significant for municipalities than for prefecture-level cities. Furthermore, the impact on different categories of urban green innovation is heterogeneous. More specifically, China’s ETS pilots have significantly spurred urban green innovation that is closely related to energy conservation and emission reduction, including alternative energy production, transportation, energy conservation and so forth. Moreover, the facilitating effect of China’s ETS pilots on urban green innovation suffers from a lagging effect, which began to show a significant positive effect in 2016. Overall, this paper identifies the effect of China’s ETS pilots on urban green innovation, and suggests that the government should consider the heterogeneity of urban green innovation when designing national ETS policies.

This study is focused on communications that come from consumer-to-consumer (C2C) ecommerce relationships. This topic is directly associated with the electronic word-of-mouth (eWOM) phenomenon. eWOM is related to the set of positive or negative opinions made by potential, actual, or former customers about a seller. The present study proposes a structural equation modeling with partial least squares (PLS-SEM) research model to analyze consumers’ opinions impact on attitude toward purchasing. This model is based on the Information Adoption Model (IAM) in combination with an ecommerce satisfaction perspective, comprising five constructs: (1) service quality, (2) ecommerce satisfaction, (3) argument quality, (4) source credibility and (5) purchase intention. The model was tested by applying the Smart Partial Least Squares (SmartPLS) software for which 116 effective data from customers of the Taobao C2C platform were used. The findings reveal that all of the defined relationships were supported, confirming the positive impact of all the proposed constructs on the purchase intention. In this respect, the findings suggest that C2C platforms should strengthen the analyzed connections to grow the business and to promote transactions. Finally, implications and limitations related to the explanatory capacity and the sample are identified.
