An analysis of the black market exchange rate in a developing economy — The case of Turkey

Zusammenfassung Eine Analyse des Schwarzmarkt-Wechselkurses in Entwicklungsl?ndern — Das Beispiel der Türkei. — Die Schwarzmarkt-Wechselkurse in Entwicklungsl?ndern sind nicht unabh?ngig davon, welche Politik betrieben wird und wie sich die anderen ?konomischen Variablen (wie Einkommen, Preisniveau und Inflationserwartungen) entwickeln. In diesem Aufsatz wird mit Hilfe türkischer Daten ein einfaches Modell entwickelt und gesch?tzt, das gleichzeitig Schwarzmarkt-Wechselkurse, Preisniveau, Realeinkommen und reale Geldmenge bestimmt. Die Ergebnisse dynamischer Simulationen zeigen, daΒ sich dann, wenn Rückwirkungen aus den übrigen Teilen der Wirtschaft zugelassen werden, die Wirkungen wirtschaftspolitischer MaΒnahmen auf die Schwarzmarkt-Wechselkurse erheblich von denen unterscheiden, die man in einem Ein-Gleichungs-Modell beobachten würde, in dem alle erkl?renden Variablen als exogen angesehen werden.

Résumé Une analyse du taux de change sur le marché noir dans une économie développante. — Les taux de change sur le marché noir dans les pays en voie de développement ne sont pas indépendants des politiques appliquées ou des autres variables économiques comme par exemple le revenu, le niveau des prix ou les expectatives d’inflation. Cet article a construit, estimé et simulé, en utilisant des données de la Turquie, un modèle simple qui simultanément détermine le taux de change sur le marché noir, le niveau des prix, le revenue réel et l’encaisse réelle. Les résultats des simulations dynamiques démontrent que, si l’on permet des rétro-actions du reste de l’économie, les effets d’un changement de politique sur le taux de change sur le marché noir sont substantiellement différents á ceux qu’on observerait avec un modèle á une seule équation dans laquelle toutes les variables explicatives sont supposément exogènes.

Resumen Un análisis del tipo de cambio negro en una economfa en desarrollo. — Tipos de cambio de mercado negro en pai’ses en desarrollo no son independientes de las polfticas aplicadas o de otras variables econ?micas tales como el ingreso, nivel de precios o expectativas de inflation. En este articulo se ha construido, estimado y simulado, sobre la base de datos de Turquia, un modelo simple que détermina simultáneamente el tipo de cambio de mercado negro, nivel de precios, ingreso real y balances monetarios reaies. Los resultados de simulaciones dinámicas muestran que, cuando se permiten realimentaciones del resto de la economia, los efectos de un cambio de pol?tica dado sobre el tipo de cambio de mercado negro son sustancialmente diferentes de aquéllos que habrian sido observados con un modelo de ecuación única que asume que todas las variables explicativas son exógenas y no permite ninguna realimentación.

     

Determinants of the Loan Loss Allowance: Some Cross‐Country Comparisons

This paper analyzes the determinants of banks' loan loss allowance for samples of U.S. banks and three non‐U.S. samples: a group of 21 countries, Canada, and Japan. The model includes fundamental (or nondiscretionary) determinants of the allowance, such as nonperforming loans, and discretionary determinants, such as income before the loan loss provision. The results suggest that the loan loss allowance is sensitive to preprovision income in almost all samples. However, the results also suggest that some variables thought to reflect fundamental factors in U.S. analysis, such as net charge‐offs, are not significant factors for non‐U.S. banks.     

Saving, Investment, and Capital Mobility in LDCs

The Coakley, Kulasi, and Smith current-account solvency model ( Economic Journal , 1996, pp. 620–7) is used to investigate saving and investment in LDCs. This model implies that saving and investment cointegrate with a unit coefficient irrespective of the degree of capital mobility. Panel and conventional unit-root tests indicate that LDC current accounts are stationary. The Feldstein–Horioka cross-section regression coefficient for LDCs is lower than the corresponding OECD coefficient, indicating different policy responses in these countries rather than higher capital mobility. Finally, adjustment toward solvency is slower in LDCs, reflecting their vulnerability to external shocks and the impact of financial repression.     

Corruption,Bureaucracy and Firm Productivity in Africa

This paper estimates the impact of corruption and poor bureaucratic quality on firm productivity for a unique dataset with firm‐specific data of more than 900 firms over 12 years for Ghana, Kenya and Tanzania. We first discuss why poor bureaucratic quality and, especially, corruption are expected to have negative impacts on firm productivity. We then employ Data Envelopment Analysis to estimate firm productivity and pooled OLS and Tobit regression analysis to estimate the effects of corruption and bureaucratic quality on firm productivity. We find that less productive firms are more likely to engage in corrupt activities; both poor bureaucratic quality and corruption reduce firm productivity; and corruption has a greater negative impact on productivity.     

Bank efficiency in South‐Eastern Europe

This study examines the cost and profit efficiency of banking sectors in six transition countries of South‐Eastern Europe over the period 1998–2008. Using a stochastic frontier approach, our analysis reveals that the average cost efficiency of South‐Eastern European banks is 68.59 percent, and the average profit efficiency is 53.87 percent. Regressions on the determinants of bank efficiency show that foreign banks are characterized by higher profit efficiency but lower cost efficiency, and government‐owned banks are associated with lower profit efficiency than domestic private banks. However, the efficiency gap between foreign‐, domestic private‐ and government‐owned banks narrows over time. We also find that the market power of a bank has a positive association with both cost and profit efficiency. Institutional development, proxied by progress in banking regulatory reforms, privatization and enterprise corporate governance restructuring, also has a positive impact on bank efficiency.     

Do investment in and the sourcing arrangement of the internal audit function affect audit delay?

This paper investigates the association between the internal audit function attributes and audit delay using a sample of 432 publicly traded firms in Malaysia in 2009. In this unique setting, we capitalize on the publicly available data concerning the investment in and the sourcing arrangement of internal audit function. We find a negative relationship between the costs incurred for the internal audit function and audit delay. However, we do not find any significant association between the internal audit function sourcing arrangements and audit delay. Additionally, we find that greater audit committee independence and longer auditor–client tenure shorten audit delay, and more frequent audit committee meetings and higher misstatements in the preliminary unaudited earnings are associated with a longer audit delay.     

Market discipline during crisis: Evidence from bank depositors in transition countries

The Central European banking industry is dominated by foreign-owned banks. During the recent crisis, for the first time since the transition, foreign parent companies were frequently in a worse financial condition than their subsidiaries. This situation created a unique opportunity to study new aspects of market discipline exercised by non-financial depositors. Using a comprehensive data set, we find that the recent crisis did not change the sensitivity of deposit growth rates to accounting risk measures. We establish that depositors’ actions were more strongly influenced by negative press rumors concerning parent companies than by fundamentals. The impact of rumors was especially perceptible when rumors turned out ex post to be founded. Additionally, we document that public aid announcements were primarily interpreted by depositors as confirmation of a parent company’s financial distress. Our results indicate that depositors react rationally to sources of information other than financial statements; this discovery has policy implications, as depositor discipline is usually the only viable and universal source of market discipline for banks in emerging economies.     

Asymmetric benchmarking in bank credit rating

This study proposes an information asymmetry hypothesis to examine why bank credit ratings vary among countries even when bank financial ratios remain constant. Countries are divided among those with low and high information asymmetry. The former include high-income countries, those in North America and West Europe regions, and those with strong institutional environment quality, whereas the latter group possess the opposite characteristics. This study hypothesizes that the influences of financial ratios on ratings are enhanced in low information asymmetry countries but reduced in countries with high information asymmetry. The sample includes the long-term credit ratings issued by Standard and Poor's from 86 countries during 2002-2008. The estimated results show that the effects of financial ratios on ratings are significantly affected by information asymmetries. Countries wishing to improve the credit ratings of their banks thus should reduce information asymmetry.     

Option‐Adjusted Delta Credit Spreads: a Cross‐Country Analysis

This study analyses the determinants of the variation in option‐adjusted credit spreads (OASs) using a unique database and enlarges the traditional analysis to include disaggregated indexes, new variables, and a complete set of markets (USA, UK, and the Eurozone). An extended set of regressors explains almost half the variability of OASs in the three markets. We find that institutional trading activity significantly affects corporate bond spreads, signalling either variation in perceptions of risk or the existence of an indirect measure of liquidity. We also find that US business cycle indicators significantly affect the variability of OASs in the UK and the Eurozone. Finally, we find evidence that stock returns have more influence on high‐yield bonds in the Eurozone than in the USA.
