Digital technology has penetrated various fields, including international trade. This study aims to analyze how barriers/openness to trade in digital services affected exports before the COVID-19 pandemic (2015-2016) and during the pandemic (2019-2020). Based on the Gravity model, exports seem...

Short-term climate conditions may affect crop yields and vintage quality and, as a consequence, wine prices and vineyards’ earnings. In this paper, we use a Computable General Equilibrium (CGE) model for Chile, which incorporates very detailed information about the value chain of the wine...

The recent economic sanctions against Russia can jeopardise the sustainability of the European Union's (EU) energy supply. Despite the EU's strong commitment to stringent abatement targets, fossil fuels still play a significant role in the EU energy policy. Furthermore, high dependency on...

We introduce a novel simulated certainty equivalent approximation (SCEQ) method for solving dynamic stochastic problems. Our examples show that SCEQ can quickly solve high-dimensional finite- or infinite-horizon, stationary or non- stationary dynamic stochastic problems with hundreds of state...

The article's main aim is to assess the impact of economic security on sustainable entrepreneurship in Central and Eastern European Countries (CEECs), including Bulgaria, Croatia, Czechia, Estonia, Hungary, Lithuania, Latvia, Poland, Romania, Slovakia and Slovenia from 2008 to 2020. The paper's...

The rapid rise in greenhouse gas emissions have become a global concern catching the attention of policy makers and researchers all over the world. Fossil fuel combustion has been named as the major source of greenhouse gas emissions, meanwhile, studies focusing on fossil fuel impact on CO2...

This study analyzes the impact of international trade on environmental efficiency. Using a data envelopment analysis (DEA) model that allows us to treat undesirable outputs and super-efficiency beyond unity, we measure the environmental efficiency of four typical air pollutants-SO 2 , NOx,...

Im Dezember 2015 findet die Klimakonferenz in Paris statt, in deren Vorfeld die Staaten bereits melden müssen, welchen Beitrag sie zum Klimaschutz nach 2020 leisten wollen. Die Autoren haben ein Modell entwickelt, mit dem sich mögliche Referenzwerte bestimmen lassen, die einerseits mit dem...

Environmental degradation and the risks from climate change have strengthened the need for cleaner forms of economic growth. Using patent, trade and output data, we measure the current size of Asia’s low-carbon economy and assess its competitiveness across key sectors. We look at three success...
