An applied endogenous growth model with human and knowledge capital accumulation for the Turkish economy
(Routledge, 2015-10-02) Voyvoda, E.; Yeldan, E.
We analytically investigate and assess the interactions between knowledge-driven growth, acquisition of human capital, and the role of strategic public policy for the Turkish economy within the context of a general equilibrium model. The model aims to investigate the public policies toward fostering the development of human capital (such as investments in education and learning) and those at enhancing total factor productivity through investments in physical capital and innovation (such as subsidies to R&D), and to study the impact of various public policies on patterns of growth, along with their likely consequences from the points of view of capital accumulation, income distribution, social welfare and economic efficiency for the Turkish economy. With the aid of the model, we seek for analytical answers to the following question: for a government constrained with its budgetary requirements, which type of public subsidiziation policies is more conducive for enhancing growth and social welfare: promotion of human capital formation through subsidies to education expenditures, or promotion of new R&D formation through subsidies to R&D investment expenditures? According to the model findings, a single-handed strategy of only subsidizing education expenditures to promote human capital formation falls short of achieving desirable growth performance in the medium to long run. Under the policy of human capital formation promotion, expected growth and welfare results are weak in the medium-to-long run unless increased human capital can upgrade the number of research personnel employed in the R&D development sector. Under these observations, it can be argued that the public policy should be directed to R&D promotion in the medium-to-long run to complement an education promotion program to sustain human capital formation.

A direct proof of the Gale–Nikaido–Debreu lemma using Sperner’s lemma
(Springer, 2022-09) Le, T.; Le Van, C.; Pham, N.-S.; Sağlam, Çağrı
The Gale–Nikaido–Debreu lemma plays an important role in establishing the existence of competitive equilibrium. In this paper, we use Sperner’s lemma and basic elements of topology to prove the Gale–Nikaido–Debreu lemma.

Economics of environmental policy in Turkey: a general equilibrium investigation of the economic evaluation of sectoral emission reduction policies for climate change
(Elsevier Inc., 2008) Telli, Ç.; Voyvoda, E.; Yeldan, E.
Research on climate change has intensified on a global scale as evidence on the costs of global warming continues to accumulate. Confronted with such evidence, the European Union set in late 2006 an ambitious target to reduce its greenhouse gas emissions, by 2020, to 20% below the level of 1990; and invited the rest of the developed economies and the developing world to take part with the Kyoto Protocol. Turkey is the only country that appears in the Annex-I list of the United Nations' Rio Summit and yet an official target for CO2 emission reductions has still not been established. Thus, as part of its accession negotiations with the EU, Turkey will likely to face significant pressures to introduce its national plan on climate change along with specific emission targets and the associated abatement policies. Given this motivation, we utilize a computable general equilibrium model for Turkey to study the economic impacts of the intended policy scenarios of compliance with the Kyoto Protocol and we report on the general equilibrium effects of various possible environmental abatement policies in Turkey over the period 2006-2020. The model is in the Walrasian tradition with 10 production sectors and a government operating within an open macroeconomy environment. It accommodates flexible production functions, imperfect substitution in trade and open unemployment. We focus on CO2 emissions and distinguish various basic sources of gaseous pollution in the model. Our results suggest that the burden of imposing emission control targets and the implied abatement costs could be quite high, and that there is a need to finance the expanded abatement investments from scarce domestic resources. Policies for environmental abatement via carbon and/or increased energy taxes further suffer from very adverse employment effects. This suggests that a first-best policy would necessarily call for a simultaneous reduction on the existing tax burden on producers elsewhere together with introduction of environmental taxes. © 2007 Society for Policy Modeling.

Labor migration and trade patterns in the presence of age composition differences across countries: an overlapping generations analysis
(2000) Uyar, Ali Emre
This study examines various effects of population growth differentials across countries by using a two country overlapping generations (OLG) general equilibrium model and shows that the resulting differences in age composition of populations provide not only a basis for trade but also incentives for international migration of labor. The analysis starts by considering autarky equilibria of the countries that are assumed to be identical except for population growth rates initially, and shows that the country with the lower (higher) population growth rate will have higher (lower) capital per worker, wage rate and lifetime utility at all times. The cases of free trade and international mobility of labor are then simulated for a comparative investigation. The simulations with the considered migration scheme reveal that the steady state value of migration rate equalizes the post-migration population growth rates in both coimtries. When trade is also taken into consideration, the results indicate that the country that is attractive to the migrants would prefer trade to migration, if it is a large country relative to the other. If both countries are equal in size, on the other hand, trade turns out to be Pareto-inferior to migration for the host country, with autarky being Pareto-superior to both trade and migration.

Public policy and growth in Canada: an applied endogenous growth model with human and knowledge capital accumulation
(Elsevier, 2015) Voyvoda, E.; Yeldan, E.
Evidence suggests that the Canadian economy is over-shadowed with lagging productivity growth and that its innovation strategy lacks a market-oriented focus; and is unbalanced and biased. We study this problem with the aid of a dynamic general equilibrium model driven by analytics of endogenous growth and investigate the viable policy options and assess the interactions between knowledge driven growth, acquisition of human capital, and the role of strategic public policy for the Canadian economy. We study alternative public policies aimed at fostering the development of human capital (investment in education) and those at enhancing investments in innovation. Based on the re-allocation effects triggered by public subsidization policies on higher education versus industry/business R&D, our results corroborate that Canadian economy is falling short of its potential in (business) technological innovation. Our analyses further imply that the most welfare enhancing policy is to have a complementary mix of education and R&D subsidization designed to avoid the trade-offs that emerge in the short run. © 2015 Elsevier B.V.
