Fast Moving Consumer Goods: Competitive Conditions and Policies

Fast moving consumer goods (FMCGs) constitute a large part of consumers' budget in all countries. The retail sector for FMCGs in Turkey is in the process of a drastic transformation. New, "modern" retail formats, like chain stores and hyper/supermarkets, have rapidly diffused in almost all major urban areas, and increased their market share at the expense of traditional formats (grocery shops, green groceries, etc.) in the last couple of decades. This rapid transformation has raised concerns about competitive conditions in the sector. This study is aimed at to shed light on competitive conditions prevailing in the FMCGs retail trade sector in Turkey. We analyze how the structure of the market is being transformed in recent years by new retail formats. The study is focused on the analysis of competitive dynamics (inter-firm rivalry, pricing and non-price policies, barriers to entry, regulatory conditions, etc.) within the sector, and draws lessons for competition policy.FMCG, competition policy, Turkey

The stress system generated by an electromagnetic field in a suspension of drops

The stress generated in a suspension of drops in the presence of a uniform electric field and a pure straining motion, taking into account that the magnetohydrodynamic effects are dominant was calculated. It was found that the stress generated in the suspension depended on the direction of the applied electric field, the dielectric constants, the vicosity coefficients, the conductivities, and the permeabilities of fluids inside and outside the drops. The expression of the particle stress shows that for fluids which are good conductors and poor dielectrics, especially for larger drops, magnetohydrodynamic effects end to reduce the dependence on the direction of the applied electric field

Diversities Between the Regulations of Turkish Accounting Standard Setters: A Brief History of Turkiye’s Twentieth Century Accounting Standardization Applications

This study examines the evolution of Turkish accounting standards to ascertain the extent of differences in Turkiye’s accounting practices among the different governmental Standard setter’s regulations during the twentieth century. The research results show that the accounting standards had set by the public corporates own self as parallel to economic policies of Turkish Ministry of Finance and money policies of Central Bank of the Republic of Turkiye before the establishment of Turkish Accounting and Auditing Standards Board in 1994. On the other hand in the last two decades of twentieth century the specific standards had set by the Ministry of Finance for tax reporting companies and Capital Markets Board of Turkiye for financial reporting companies have the significant differences.Standardization; Accounting in Turkiye

Price and Income Elasticities of Turkish Export Demand : A Panel Data Application

In this paper, price and income elasticities of export demand are calculated. The study is extended to sectoral and country specific export demand functions. The paper presents some panel unit root and cointegration tests, which have been studied extensively in recent years. The major aim of this study is to find the price and foreign income elasticities of aggregate export demand. According to the estimation results, the real exchange rate elasticity of total export demand is found to be less than one, whereas the income elasticity is found to be greater than one.Panel Unit Root Test, Panel Cointegration Test, Income and Real Exchange Rate Elasticities

Regularity properties of the cubic nonlinear Schr\"odinger equation on the half line

In this paper we study the local and global regularity properties of the cubic nonlinear Schr\"odinger equation (NLS) on the half line with rough initial data. These properties include local and global wellposedness results, local and global smoothing results and the behavior of higher order Sobolev norms of the solutions. In particular, we prove that the nonlinear part of the cubic NLS on the half line is smoother than the initial data. The gain in regularity coincides with the gain that was observed for the periodic cubic NLS \cite{et2} and the cubic NLS on the line \cite{erin}. We also prove that in the defocusing case the norm of the solution grows at most polynomially-in-time while in the focusing case it grows exponentially-in-time. As a byproduct of our analysis we provide a different proof of an almost sharp local wellposedness in $H^s(\R^+)$. Sharp $L^2$ local wellposedness was obtained in \cite{holmer} and \cite{bonaetal}. Our methods simplify some ideas in the wellposedness theory of initial and boundary value problems that were developed in \cite{collianderkenig, holmer,holmer1,bonaetal}.Comment: 30 pages.
