Abstract Using a production function approach, we estimate that the economic value of biotic pollination to Georgia’s agriculture increased from $425 million in 2009 to $488 million in 2017 in real terms. We perform spatial analysis to reveal county-level spatial patterns and temporal trends in that value. Using a unique set of pollinator survey data, we also compare the locations of biotic pollinators to the areas they bring the most economic value to, which provides insights on the variation in the dependency of the crop mix to pollination services.

Setu Patok is a small lake located in Setu Patok Village, Mundu Sub District, Cirebon Districts, West Java Province. Currently it is used as a source of agricultural irrigation, fishing ground, and tourism object. However, all these uses have not been carried out optimally. In this study, the benefits studied were only devoted to fishery utilization in order to find out the Setu Patok Fisheries Economic Value (NEP). The study uses the Production Function Approach or Market Based Aproach method, which measures the value of environmental goods and services based on market value. The study used primary data through direct interviews with fishermen. As a result, it was found that the Setu Patok NEP was IDR 421,494,000/year.Setu Patok adalah sebuah danau kecil yang berada di Desa Setu Patok, Kecamatan Mundu, Kabupaten Cirebon, Provinsi Jawa Barat. Saat ini dimanfaatkan sebagai sumber irigasi pertanian, perikanan tangkap dan objek wisata. Namun, semua pemanfaatan tersebut belum dilakukan secara optimal. Dalam penelitian ini, manfaat yang diteliti dikhususkan hanya pada manfaat langsung khususnya perikanan tangkap dengan tujuan untuk mengetahui Nilai Ekonomi Perikanan (NEP) Setu Patok. Penelitian menggunakan metode Production Function Approach atau Market Based Aproach yaitu mengukur nilai barang dan jasa lingkungan berdasarkan nilai pasar. Penelitian menggunakan data primer melalui wawancara langsung dengan para nelayan. Hasilnya, didapat bahwa NEP Setu Patok adalah sebesar Rp 421.494.000/tahun.

AbstractWe propose an improved method to assess the economic value of unpaid housework and childcare. Existing literature has typically assigned a minimum, generalist or specialist’s wage, or the performer’s opportunity cost to the hourly value of these activities. Then it was used to calculate macro-level value based on the number of hours spent in this work. In this paper, instead of imputing an average or minimum wage for housework and childcare to determine a value to the work, we use the actual local wage rate requested for these services from providers on online platforms. Applying this method to Austrian Time Use Survey data shows that the value of unpaid childcare and housework, had it been paid, would be equivalent to about 22% of the 2018 GDP.
