O47 - Empirical Studies of Economic Growth; Aggregate Productivity; Cross-Country Output ConvergenceReturn

Recent studies tend to scrutinize the convergence and growth patterns of various socioeconomic variables among countries or regions, as well as their per capita income. This study as a new approach examines the growth rate and convergence inclination of real per capita exports among the 81 provinces of Türkiye for the period 2004–2021. The role of imports and their subcategories (intermediate, capital, and consumer goods) is also considered in this context. The results of the non-spatial panel model show that real per capita exports converge among provinces in both absolute and conditional terms. On the other hand, while total imports as well as imports of intermediate goods and capital goods contribute to export growth and convergence of the provinces, imports of consumer goods have no effect. According to the results, spatial interaction among provinces is notable. The results do not change significantly depending on the estimates of the DSAR model (Dynamic Spatial Autoregressive Model), identified as the appropriate specification.

This study assesses the impact of foreign direct investment (FDI) inflows on economic growth and domestic investment in a panel of Economic Co-operation and Development (OECD) countries during the period of 1990–2017 by utilizing the method of fixed-effects and system generalized method of moments (GMM). The findings show that FDI inflows are positively and significantly associated with the economic growth of the host economy. When considering the origin of FDI, we find that FDI from developed countries contributes to the growth rate in the receiving economy, while FDI from developing countries shows no significant effect. Importantly, FDI does not appear to crowd in or out domestic investment. Only FDI from developed countries is associated with crowding in of domestic investment.

Climate change poses a serious threat for aquacultural productivity. Employing the Autoregressive Distributed Lag (ARDL) model, this research aims to evaluate the economic impact of climate change on aquaculture in Vietnam, drawing on time series data from 1981 to 2013 and including aquaculture yield, acreage, investment, labor, temperature, rainfall, and damage costs to aquaculture caused by natural disasters. The results show that aquaculture yield depends not only on the current value of inputs, but also on their lag values and the yield itself. The results also show that rainfall, storm surges and tropical cyclones negatively affect aquaculture production. After any natural disaster, it takes at least two years to recover from the repercussions for productivity and return to the previous norm. To reduce the vulnerability of aquacultural communities, this study suggests that the state could establish a climate resilience fund specifically for small and medium-scale aquaculture farmers, providing special financial support for those affected by natural disasters.

This contribution deals with issues of corporate taxation in relation with economic growth. Its main objective is to quantify and analyse the relation of corporate taxation and economic growth using of OECD countries. The corporate tax rate is approximated by effective corporate tax rates such as corporate tax quota, marginal effective and average tax rates as determined by micro-forward looking approach and the alternative approach World Tax Index. The relation of taxation and economic growth is verified using an econometric model based on panel regression methods and tests using a dynamic panel. The model has shown a negative impact on economic growth for all six of the selected corporate tax approximators under the assumed significant level. A quantitatively higher negative impact has been verified in the case of labour taxation.

This paper investigates the β -convergence in the trade volumes of EU countries. We focus on a different approach to convergence analysis, namely trade's contribution to convergence. Neoclassical growth theory assumes there will be a convergence process among the economies, even in absence of trade. Trade relations might, however, speed up this process. We use panel data for trade volumes of 26 EU countries and test the presence and the speed of β -convergence pattern on SITC sectors 6 and 7 trade categories. The implied speeds of unconditional convergence of the export volume per capita are about 0.05-0.06 (implying half-lives around 12-13 years). When accounting for the country- or time-period specific effects, we can observe relatively high convergence rates (with half-lives somewhere around 2-4 years).
