A Dynamic CGE Model: An Application of R&D- Based Endogenous Growth Model Theory

An R&D based endogenous growth - applied general equilibrium model is developed from an underlying analytical model which combines Romer's capital variety with Grossman and Helpman's multi-sector open economy model. The transitional dynamics of the analytical model are derived. For numerical implementation, a time discrete empirical model, with an Armington structure, is fit to East Asian data of the social accounting matrix variety. Simulations of trade reform are performed and their static and dynamic effects compared. The transition paths of the state variables are found to have a half-life of five to six periods. A solution of the Social Planner's problem, and interventions which seek to obtain this outcome from the decentralized model are also obtained'.Applied General Equilibrium, Trade, Growth, International Relations/Trade, F11, 031, 041,

Interest Rate Smoothing and Macroeconomic Instability under Post-Capital Account Liberalization Turkey

Cataloged from PDF version of article.This paper considers the interest rate policy of the Central Bank of the Republic of Turkey (CBRT) in the post-financial liberalization and deregulation era. We find that (1) the Bank's interest rate smoothing tendency is the main determinant of its monetary policy in this period, (2) the CBRT does not seem to be responsive to the developments in real economy (output), and (3) although inflation targeting central banks are not supposed to pay attention to exchange rates, the CBRT appears to be slightly responsive to changes in real exchange rate. In answer to the question of whether there is a deeper underlying Structural constraint binding the CBRT's "independence," it seems clear that the global financial system is restricting the ability of the central banks to pursue "independent" policy objectives

Estimating some population parameters and stock assesment of spiny butterfly ray, Gymnura altavela (Linnaeus, 1758) the Levant Basin coast (Northeastern Mediterranean)

The purpose of this study was to investigate the morphometric characteristics, growth, mortality and exploitation rate of the spiny butterfly ray (Gymnura altavela Linnaeus, 1758). The study was conducted using 284 specimens from the coastal waters of the Levant Basin (the northeastern Mediterranean). Samples were collected monthly between July 2014 and June 2015 using a bottom trawl from the following depth strata: 0-10m, 10-20m, and 20-50m. The following measurements were taken total length (TL), disc length (DL), disc width (DW) distance from nose tip to eye (NE), nose tip to mouth (NM, cm), width of mouth (MW, cm) where Y is the various dimensions (TL; W; DL; DW; NE; NM; MW, respectively) and X is the total length estimated by linear regression analysis. Length-weight and disc width-weight relationships were W = 0.097 * TL 3.2070 and W = 0.084 * DW 3.169 for total individuals. The von Bertalanffy growth function contained in DW was DW? = 136.50cm K = 0.230 year -1 t 0 =-0.492year -1 for total individuals. The total mortality (Z) was 0.91year -1 , the natural mortality (M) was 0.41year -1, and the fishing mortality (F) was estimated to be 0.51year -1 . The exploitation rate (E) was calculated as 0.55 year -1 for all obtained individuals. © 2018, Agricultural Research Communication Centre. All rights reserved

A preliminary study on the reproduction of the rabbitfish (Siganus rivulatus (Forsskal, 1775)) in the Northeastern Mediterranean

This study was carried out to identify some aspects of the reproductive cycle of the rabbitfish (Siganus rivulatus) inhabiting the northeastern Mediterranean. For this reason, monthly sampling was conducted between February 1995 and June 1996, and a total of 473 specimens were used. By using the monthly changes in the values of the gonadosomatic index (GSI) and Condition Factor (K), it was found that their reproduction takes place during July and August. The mean diameter of ripe gonadal eggs was 0.44 mm; and mean fecundity and its standard deviation was found to be 434761±181006. Fecundity-total length, fecundity-total weight and fecundity-age relationships were also estimated using regression analysis as follows: Total Length (cm) F=0.49 * L4.61 (r=0.96) Total Weight (g) F= -57584.67 + 4851.96 * W (r=0.96) Age (years) F= -1029631.33 + 255261.18 * A (r=0.64)

Length-weight relationship for five elasmobranch species from the Cilician Basin shelf waters (Northeastern Mediterranean)

In this study, elasmobranch length-weight relationships were estimated for five species caught between June 1999 and May 2003 from the Cilician Basin shelf waters (Northeastern Mediterranean): Raja clavata, Raja radula, Raja asterias, Dasyatis pastinaca, and Gymnura altavela. There were no significant differences between males and females, and only Raja clavata females showed isometric growth. © 2007 The Authors

Age, growth and feeding of the common stingray (Dasyatis pastinaca, L., 1758) in the Cilician coastal basin, northeastern Mediterranean Sea

Growth and feeding of stingray (Dasyatis pastinaca) were studied using 346 specimens from the Cilician Basin coastal area (northeastern Mediterranean). Age classes between 0 to XII were found. The total length of all specimens ranged from 14.6 to 100.9 cm, and total weight was between 22.5 and 6800 g. Total length (TL)-weight (W) and disc width (DW)-weight (W) relationships were W = 0.0033*L3.1429 and W = 0.0039*DW3.4914, respectively. The age data, derived from central readings, were used to estimate the von Bertalanffy length and weight growth parameters. The results were L? = 294.9 cm, W? = 198690.1 g, K = 0.029 year-1; t0 -2.2 year. The D. pastinaca diet was composed mainly of crustaceans. © 2008 Blackwell Verlag, Berlin

Turkish agriculture under structural adjustment. A general equilibrium analysis

The economic effects of the post -1980 Turkish reform program on the agricultural sector are analysed using a two-level quantitative analysis : A CGE model of the domestic economy at the macro level is supplemented by a micro level, multi-market , multi-regional model of the agricultural sector. The modelling exercises investigate the burden of adjustment faced by the rural economy during the 1980s, and analyse the medium term consequences of a massive program of public investment known as the Southeastern Anatolia Project. The modelling analysis shows that the Turkish reform program relied heavily on a worsening income distribution and increased agricultural taxation and reveals that there was a significant trade-off between food security and the export promotion targets.L'agriculture turque confrontée à l'ajustement structurel. Analyse en termes d'équilibre général. La Turquie s'est engagée en janvier 1980 dans un ambitieux programme d'ajustement structurel pour rééquilibrer ses comptes macroéconomiques et revitaliser un appareil productif à bout de souffle. Pendant des décennies, l'agriculture turque avait fonctionné sous un étroit contrôle de l'État. A la suite de la politique d'ajustement, le secteur s'est trouvé plongé dans un environnement économique devenu concurrentiel avec l'ouverture du pays aux importations, la détermination des prix par le marché et la baisse des subventions. La mise en œuvre de cette politique a eu des conséquences très dures pour le secteur agricole, où l'Etat a sérieusement réduit son intervention, tant en ce qui concerne le sou¬ tien des prix que leur contrôle. L'évaluation des effets économiques du programme d'ajustement structurel sur l'agriculture turque est réalisée à l'aide d'un modèle d'équilibre général et d'un modèle micro-économique, multirégional et multimarché du secteur agricole. Ces modèles permettent de calculer le coût de l'ajustement pour le secteur et analysent les conséquences à moyen terme du projet "Anatolie Sud-Est", où l'État a engagé une politique d'investissements massifs. Les simulations réalisées à l'aide du modèle d'équilibre général montrent l'importance des relations qui conditionnent la demande finale du pays. Ainsi, la demande finale agrégée baisse lorsque le gouvernement réduit son train de vie ou les transferts destinés aux ménages. Une telle situation entraîne des tensions inflationnistes, même si elle se traduit par l'effet inverse sur les marchés des produits et des facteurs. On peut aussi faire varier le taux de change pour rééquilibrer les comptes macroéconomiques. Avec les hypothèses faites, le modèle conclut à la nécessité d'une dévaluation. L'introduction de cette dévaluation dans le modèle sectoriel se traduit par une modification très nette de la répartition des productions en faveur des cultures d'exportation. La production de toutes les cultures diminue, sauf celle des cultures industrielles. De plus, il y a un développement des exportations au détriment de la consommation intérieure. La modélisation montre que la politique d'ajustement structurel de la Turquie a été réalisée au prix d'une aggravation des disparités de revenu et d'une taxation de l'agriculture. D'autre part, elle met en évidence le conflit existant entre les objectifs de sécurité alimentaire et de promotion des exportations.Cakmak Erol H., Yeldan A. Erinc.

Growth, mortality rate and exploitations rate of the deep-water rose shrimp (Parapenaeus longirostris) in the Babadıllimanı bight(Silifke-Mersin) [Babadıllimanı koyu'ndaki (Silifke-Mersin) derinsupembe karidesi (Parapenaeus longirostris)'nin büyüme,ölüm oranları ve stokdan yararlanma düzeylerininbelirlenmesi]

This study was carried out through monthly deep trawls applications in the waters of 0-50m, 50-100m and >100m of depths in Babadillimani Bight between June 1999-April 2000. There was a linear relationship between carapace length and total length in males and females CL= -0.2257+0.2243*TL (R2= 0.9216, n= 923) for males, CL= -0.2148+0.222*TL (R2= 0.9649, n=2859) for females, and CL= 0.0952+0.2223*TL (R2= 0.9652, n= 3886) for total individuals. As to equation of relationship between carapace length and weight, it was W= 0.0015*CL2.6252 for males, W= 0.0009*CL2.8190 for females, and W= 0.001*CL2.7954 for total individuals. The von Bertalanffy growth constants in length was CL? = 31.20mm, K= 0.76/year, t0= -0.386 year, C= 0.65, WP=0.65 for males; CL? = 32.30mm, K= 0.77 year-1, t0= -0.387 year, C= 0.80, WP= 0.57 for females; and CL = 32.10mm, K= 0.76 year-1, t0= -0.394 year, C= 0.60 and WP= 0.65 for total individuals including juveniles as well as sexually maturated ones. In the study, for all the individuals of the species, the total (Z), natural (M) and fishing (F) mortality coefficient and exploitation rates (E) were determined as 4.00, 1.29, 2.71 and E= 0.67 year-1, respectively
