Abstract This article uses Russian regional data to estimate the determinants of the informal economy and to examine the relationship between the informal economy and the growth of legally registered small private enterprises during the transition period. After obtaining an estimate of the size of the informal economy in each Russian region from 1992 to 1999, an analysis is performed to find whether reform progress and institutional qualities account for the informal economy. An evaluation of th

To understand the ecology and spatial distribution patterns of Shorea roxburghii, a vulnerable plant on the IUCN's Red List, this study was conducted in a Vietnamese evergreen forest. To collect data, a 100 m 100 m plot was established in the Tan Phu protected forest, in South Vietnam. Relative density, relative basal area, and importance value index (IVI) were determined for each species. Individuals were categorized by juvenile (dbh < 5 cm), subadult (5 cm dbh < 10 cm) and adult (dbh 10 cm) li

This paper analyzes the factors influencing whether individuals have delegative democratic attitudes (i.e. supporting strong executive power with little oversight from the legislature). Roughly up to 50% of voters in East Asia have delegative democratic attitudes, which are known to undermine democratic governance in new democracies. Understanding delegative democratic attitudes is thus closely linked to the question of why delegative democracy persists. Our theoretical analysis suggests that de

As the economy becomes more open to trade, aggregate productivity can increase by driving out the least productive firms (the selection effect). Since the selection effect reallocates resources toward the more productive firms, this process can be hindered by rigidity in domestic labour market institutions. Based on the selection effect by Melitz (2003), this article empirically examines how rigidity in labour market institutions affects the consequence of trade on aggregate productivity. Findin

Abstract This study uses firm‐level panel data for South Korea for the period 2006–2015, to investigate changes in firms' sourcing behaviors after these firms start exporting. The data studied includes detailed information on firms' export status, whether their purchases of intermediate inputs were domestic or from foreign markets, and whether the supplier firms were affiliated or non‐affiliated. To estimate the effects of exporting on firms' sourcing strategies, we employ a difference‐in‐differ

이 논문에서는 우리나라 적지적수 연구사에 관한 사료를 제시하였다. 필자는 조선시대의 임금에 대한 진상을 목적으로 한 적지적수사와 일제강점 초기의 간이적인 적지적수 연구 및 실시사례, 강점중기에 이르러서는 조선수목죽류 기후상적지도, 후기에는 속성수의 절지식재시험 및 지역별 조림수종 선발시험 등에 관한 주요 자료를 해외에서 수집 발굴하였다. 조선수목죽류 기후상적지도는 아직까지 국내에 알려지지 않은 자료로서 향후 우리나라 산지의 지원화 및 산불 피해지 복구조림, 남북통일을 대비한 북한지역 녹화사업의 기초자료로서 뿐만 아니라 고유임상 및 식생연구 등에도 유용하게 사용될 것으로 기대된다. Historical Documents on Proper Tree Selection System of Korea were collected in Japan and introduced in this review. Products of some pine species and fruit were used for l

<title>Abstract</title> This study examines the effect of political polarization, measured by the dispersion of self-reported political ideologies, on economic growth. Using a panel of 75 countries from 1990 to 2019, we find that political polarization has a negative effect on economic growth through its effect on private investment, human capital investment, and total factor productivity. We reveal that state capacity—the government’s ability to achieve intended policy goals—mitigates the adver
