As scarce environmental resources necessarily put a constraint on population growth, we use more realistic population growth dynamics which contemplates a feedback mechanism between population growth rate and resource availability. We examine the local stability properties in overlapping generations resource economies which takes this feedback mechanism into account. The results indicate that Hopf bifurcation may arise without requiring logistic regeneration or unconventional constraints on parameter values. In particular, Hopf bifurcation is encountered under convex-concave dependence of carrying capacity on the resource availability.

The aim of the study is to explore the effect of innovation on growth of firms placed at different percentiles of the growth distribution in manufacturing and services sectors in Turkey. We show that innovation crucially adds to the likelihood of being a high growth firm. Innovation efforts are found to have more pronounced effects on growth performance of firms at the upper end of the distribution of growth. Results indicate that compared with services, manufacturing firms are influenced more by R&D whereas innovation outputs are more beneficial for services firms.

The aim of this study is to investigate of the relationship between foreign direct investment and women employment. Focusing on services sector with the highest rate of women employment, we empirically attest whether foreign direct investment creates job opportunities for women and decrease the gender inequality for women in terms of employment. Propensity Score Matching techniques and Difference-in-Difference techniques are employed to firm level data for Turkish services industry over 2003-2012. The results of the study suggest that foreign direct investment increase women employment and create good jobs for women.

Utilizing a comprehensive dataset for Turkish manufacturing firms, we analyse differentials in the post-entry effects on productivity of exporting to markets with different income levels. We employ propensity score matching techniques with multiple treatments, together with a differences-in-differences (DiD) methodology. Controlling for firm level mark-ups, we explore whether the post-entry effects on productivity are driven by changes in physical productivity. The results confirm the learning-by-exporting hypothesis, and suggest physical productivity gains, in particular for exports to high income countries as opposed to middle low-income countries, even after controlling for the composition of exports. This suggests that where a firm export does matter for productivity growth.

Utilizing a comprehensive dataset for Turkish manufacturing firms over 2003-2011, we analyse the differentials in the post-entry effects of exporting to markets with different income levels. We employ propensity score matching techniques together with a differences in differences methodology. Controlling for the quality of exports, we explore whether the post-entry effects on productivity are driven by changes in real productivity, as opposed to quality/price markup effects. Our results confirm the learning by exporting hypothesis and suggest real productivity gains in particular for exports to high income (HI) countries as opposed to middle low income (MLI) countries even after controlling for the composition of exports. This suggests that where a firm exports does matter.

This paper focuses on self-selection into trade by exporting and importing firms, and on the presence of differential variable and sunk costs between exporters and importers across different categories of imports. The authors use a rich and recent dataset for Turkish manufacturing firms for the period 2003–2010. This allows them to provide a comprehensive analysis of firm heterogeneity and the connection between firm-level performance and international trade. They provide evidence on the remarkable heterogeneity across firms where only-importers (importers) perform better than only-exporters (exporters). The authors detect a self-selection effect for both importing and exporting firms with a stronger effect for importers. The results suggest that the nature of sunk costs varies between importing and exporting activities with importers facing higher sunk costs. Tariffs represent a potentially important source of variation in the variable costs of trading. When taking the tariffs face...

Calismanin amaci Turkiye’deki orta gelirli sinifin genel durumunu belirlemek ve orta gelirden dusuk gelire ve yuksek gelire gecis olasiligini etkileyen sosyoekonomik ve demografik faktorleri tespit etmektir. Analizlerde 2005-2013 yillari arasindaki TUIK tarafindan duzenlenen gelir ve yasam kosullari anketleri kullanilarak probit modeli ile tahminler yapilmistir. Analiz sonuclari orta gelirden dusuk ve yuksek gelire geciste yas, cinsiyet, egitim, SGK’ya kayitlilik, hane sayisi, hanedeki cocuk sayisi, hanede elde edilen gelir tipi ve calisilan sektorlerin etkili oldugunu gostermektedir.

This paper investigates whether inflows of FDI and innovative activities act as a channel of knowledge spillovers in improving quality of countries’ output. In measuring export quality, sophistication of a country’s export basket is utilized. Utilizing panel data of countries for the period 2002–2015 and applying GMM methodology, the results indicate that the level of financial development, the quality of human capital and globalization of a country have a determinant role on the relation between knowledge spillover channels and the quality of exports. Patent applications generally positively affect sophistication of exports. FDI serves as a channel for knowledge spillovers to benefit the sophistication level of exports only for developed, more educated, financially developed and globalized countries.

PurposeThis paper aims to examine the effect of exports on women's employment rate for Turkish manufacturing firms over a recent period of 2003–2015.Design/methodology/approachThe authors establish treatment models and use propensity score matching (PSM) techniques together with difference-in-difference methodology.FindingsThe results of the study indicate that starting to export increases women’s employment rate for manufacturing firms. Gains in female employment rates are observed for the firms operating in low and medium low technology intensive sectors, low-wage sectors as well as laborlabor-intensive goods exporting sectors.Originality/valueThe authors complement previous literature by utilizing a rich harmonized firm-level dataset that covers a large number of firms and a recent time period. The authors distinguish between several sub-samples of firms according to technology intensity of the sector in which they operate, wage level and factor intensity of exports and inves...

Bu çalışmada uluslararası ticaretteki ürün ve ülke çeşitlenmesinin firma performansı üzerindeki etkileri, ihracat ve ithalatın getirilerindeki farklılıklara da odaklanılarak analiz edilmektedir. Türkiye imalat sanayi firmaları için 2003-2010 dönemine ait zengin ve güncel bir veri seti kullanılmaktadır. Çalışmadan elde edilen sonuçlara göre firmalar ürün/ülke çeşitlenmesi bakımından ne kadar gelişmişlerse o kadar iyi performans göstermektedirler. İthalattaki çeşitlenme firmalara ihracattaki çeşitlenmeye göre daha fazla yarar sağlamaktadır. Bununla birlikte dış ticaretteki ülke çeşitlenmesinin ortaya çıkardığı performans primleri ürün çeşitlemesine göre daha yüksektir.

We examine the effects of international trading activities of firms on creating productivity gains in Turkey by using a recent firm-level data set over the period 2003–2010. We establish treatment models and investigate the productivity improvements of firms through trade by using propensity score matching techniques together with difference-in-difference estimates. Three different groups of treatment are constructed: (1) firms that are involved only with import activities, (2) firms that are involved only with export activities and (3) firms that are involved with both export and import activities. The results of the study suggest that both exporting and importing have positive significant effects on total factor productivity (TFP) and labour productivity(LP) of firms. Importing is found to have a greater impact on productivity of firms compared to exporting. Further, two-way trade is found to have more significant effects than those of one-way trade on firm productivity. Finally,our results indicate that international trade has greater impact on LP rather than TFP of firms.

This paper focuses on self-selection into trade by exporting and importing firms, and on the presence of differential variable and sunk costs between exporters and importers across different categories of imports. In addition, we consider the role of intensive and extensive margins be this with respect to products or countries. We use a rich and recent data set for Turkish manufacturing firms for the period 2003-10. This allows us to provide a comprehensive analysis of firm heterogeneity and the connection between firm-level performance and international trade. We provide evidence on the remarkable heterogeneity across firms where only-importers (importers) per-form better than only-exporters (exporters). We detect a self-selection effect for both importing and exporting firms with a stronger effect for importers.The results suggest suggest that the nature of sunk costs varies between importing and exporting activities with importers facing higher sunk costs. Tariffs represent a potentially important source of variation in the variable costs of trading. When taking the tariffs faced by firms into account, we find that the self-selection effect associated with sunk costs is still present but greatly reduced with a smaller reduction for importers compared to ex-porters.
