The impacts of bank-specific and macroeconomic variables on the capital adequacy ratio: evidence from Islamic banks

The study investigates the relationship between the capital adequacy ratio (CAR) and different bank-specific and macroeconomic variables for 28 Islamic banks. We document that there is a statistically significant positive relationship between the CAR and the bank-specific and macroeconomic variables. In particular, bank-specific variables such as ROA, ROE, leverage, credit risk and size show a strong association with the CAR, while on the macroeconomic side, inflation, market capitalization and exchange rate have an impact on the average Islamic bank in our sample study. Furthermore, we run another model (equity to assets ratio) as dependent, with similar control variables, and the results reveal that, except for inflation, all the variables that have a significant effect on the CAR also influence the equity to assets ratio.     

Withstanding financial crises: would trade partners help or hurt?

This article provides new empirical evidence on the losses of real activity caused by various financial shocks. Spillover effects due to foreign trade linkages deserve special attention. To this end, we estimate a modify auto-regressive process and a Seemingly Unrelated Regression Equations estimator is used to account for the dependency of one’s country growth on its trade-weighted partners growth. We run estimations on a set of currency collapses, banking crises and sovereign defaults in 49 advanced and developing countries from 1978 to 2011. The trade-weighted foreign demand effect mitigated the economic downturn following a banking or a sovereign debt crisis in all countries, while only the advanced ones benefited from it after a currency collapse. Trade-based spillover effects make banking crises more costly in the developing countries, in those that liberalize their financial account. It contrasts with what is observed during currency or sovereign debt crises.     

A money demand system for German M3

A small macroeconomic model is constructed starting from a German money demand relation for M3 based on quarterly, seasonally unadjusted data for the period from 1976 to 1996. In contrast to previous studies we build a vector error correction model for M3, GNP, an inflation rate and an interest rate spread variable to represent opportunity costs of holding money. Furthermore, import price inflation is added as an exogenous variable. The model is used to analyze the relation between money growth and inflation by means of an impulse response analysis.We thank Gerd Hansen for soliciting two anonymous referee reports on an earlier version of this article and thereby helping in the editorial process for this volume.

Asymptotic confidence bands for the estimated autocovariance and autocorrelation functions of vector autoregressive models

This paper provides closed-form formulae for computing the asymptotic covariance matrices of the estimated autocovariance and autocorrelation functions of stable VAR models by means of the delta method. These covariance matrices can be used to construct asymptotic confidence bands for the estimated autocovariance and autocorrelation functions to assess the underlying estimation uncertainty. The usefulness of the formulae for empirical work is illustrated by an application to inflation and output gap data for the U.S. economy indicating the existence of a significant short-run Phillips-curve tradeoff.First version received: November 2002/Final version received: September 2003     

Financial development shocks and contemporaneous feedback effect on key macroeconomic indicators: A post Keynesian time series analysis

In this paper we take into account the role of the banking system, credit and stock market in stimulating aggregate demand in post Keynesian tradition. According to the results of impulse response analysis; it appears all three financial development indicators contributed as expected in improving macroeconomic performance of South Korean economy. Stock market capitalisation and domestic credit availability are strongly responsible for stimulation of investment, saving and productivity Growth in Hong Kong. The UK financial system seems vulnerable to future shocks, whether by shocks in the credit markets or stock markets.     

Causality and normal states in economics and other disciplines

In this article, past and recent accounts of causality and the notion of normal state adopted in various disciplines are linked to the philosophical insights of John Stuart Mill and Piero Sraffa in order to provide a particular focus on economic theory. A simple neuron model and the theory of natural price in Adam Smith are taken as typical applications of causality plus normality and serve to argue that the deviations from a normal state can play two roles in economic theory: (1) the selecting of causes and causal explanations and (2) agency represented by the variables of a causal model.     

An analysis of wine and food consumption dynamics in Japan using a vector error correction model

This article provides an analysis of long-term equilibrium relationships between wine and food-related consumptions in Japan through the vector error correction model. Utilizing longitudinal data from 1970 to 2009, the analysis suggests that wine consumptions and food-related consumptions are co-integrated. The investigation of orthogonal impulse response functions suggests that food-related items, such as bread, vegetables and eating out are positive factors for wine consumptions. With the expansion of wine consumption and diversification of food consumption patterns, wine is deemed to have gained its place in Japanese ordinary life, regardless of the general state of economy. The estimated results also provide a supporting evidence for previous cross-sectional study findings by others that wine consumers tend to have healthier diet. Despite the downward forecasts for economic performance and some food items, wine consumption is predicted to grow continuously.     

Modelling monetary transmission in UK manufacturing industry

This paper studies the transmission of monetary policy to industrial output in the UK. In order to capture asymmetries, a system of threshold equations is considered. However, unlike previous research, endogenous threshold parameters are allowed to be different for each equation. Such an approach may be appealing from an economic point of view and is shown to be of importance after suitable econometric evaluation. Results show evidence of cross-sectional differences across industries and asymmetries in some sectors. These findings contribute to the debate about the importance of alternative economic theories to explain these asymmetries and support the use of a sectorally disaggregated approach to the analysis of monetary transmission.     

Ageing shocks and short-run regional labour market dynamics in a spatial panel VAR approach

Using a flexible spatial panel VAR model for a small-scale labour market system, we investigate the dynamic interdependences between changes in the demographic structure and the labour market performance of a regional economy. With a particular focus on ageing shocks, we describe an increase in the share of elderly in regional population due to exogenous changes in the institutional context, such as pension reforms. The regional labour market implications of an ageing shock are then tested with regard to the effects on employment growth, unemployment and labour participation rate. Our results based on a sample of 71 Scandinavian regions point to negative regional labour market effects of an ageing shock implying a reduction in employment growth and a temporarily declining labour participation rate, while the unemployment rate increases. Importantly, spatial spillovers amplify these negative impacts through a marginalization of macro-regional labour markets. As a robustness check, we reverse the causal ordering and analyze the responses to a positive macroeconomic shock which initially increases employment growth. We find direct and spatially indirect adjustment patterns characterized by a reduction of the unemployment rate, an increase in the labour participation rate and a decrease in the share of elderly in the population.     

The effect of exchange rate changes on trade balances in the short and long run

Using generalized impulse response functions, this study tests for the trade J‐curve for three transitional central European countries – the Czech Republic, Hungary, and Poland – in their bilateral trade with respect to Germany. Our findings suggest that for each country there are some characteristics associated with a J‐curve effect: after a (real or nominal) depreciation the export‐to‐import ratio briefly drops to below its initial value within a few months and then rises to a long run equilibrium value higher than the initial one.     

Interactions between real economic and financial sides of the US economy in a regime-switching environment

This objective of this study is to examine the linkages between real (economic) and financial variables in the United States in a regime-switching environment that accounts explicitly for high volatility in the stock market and high stress in financial markets. Since the linearity test shows that the linear model should be rejected, we employ the Markov-switching VECM to examine the same objective using the Bayesian Markov-chain Monte Carlo method. The regime-dependent impulse response function (RDIRF) highlights the increasing importance of the financial sector of the economy during stress periods. The responses and their fluctuations are significantly greater in the high-volatility regime than in the low-volatility regime.

我国服务价格与物价总水平波动互动关系研究

通过采用1992～2011年全国居民消费价格总水平、服务价格上涨率时间序列数据,建立VAR模型,运用脉冲响应函数和预测方差分解的方法对服务价格波动和我国物价总水平波动互动关系进行实证研究。计量结果表明,服务价格波动与我国物价总水平波动间存在单向因果关系,服务价格波动是我国物价总水平波动的格兰杰原因。服务价格波动1%,会带来物价总水平0.5902%的波动。VAR模型的动态分析表明,服务价格波动对我国物价总水平波动约有5年的影响。方差分解的结果说明服务价格波动对我国物价总水平波动的贡献率最大达到38.4%。要防止我国物价总水平大幅度波动,政府需要更加重视产业价格政策。     

Effects of mineral-commodity price shocks on monetary policy in developed countries

This article investigates effects of changes in mineral commodity prices on monetary policy. Using macroeconomic data from three mineral-producing countries (Australia, Canada and New Zealand) and two non-mineral-resource countries (USA and UK), I estimate the impulse response functions of the policy interest rates and the core consumer price index (CPI) inflation rates to mineral-commodity price shocks. I find that the central banks in both groups of the examined countries significantly respond to mineral-commodity price shocks. In responses to an unexpected 10% increase in mineral commodity prices, the central banks are estimated to increase their policy interest rates by approximately 0.8 percentage points. Moreover, the central banks seem to take anticipatory policy reactions to control core CPI variations triggered by these shocks. Thus, mineral commodity prices would act as important determinants of the monetary policies in both groups of the examined countries. These findings would be useful for analysing Taylor rules in their countries. However, effects of the increase in their policy interest rates on core CPI inflation cannot be identified for the examined countries.     

Real interest rate linkages in the Pacific-Basin region

This paper examines the linkage of real interest rates of a group of Pacific-Basin countries with a focus on East Asia. We consider monthly real interest rates of US, Japan, Korea, Singapore, and Thailand from 1980 to 2006. The impulse response analysis and half-life estimation are conducted in a multivariate setting, adopting the bias-corrected bootstrap as a means of statistical inference. It is found that the degree of capital market integration has increased after the Asian financial crisis in 1997. The overall evidence suggests that the crisis has substantially changed the nature of the short run interactions among the real interest rates. Before the crisis, both the US and Japanese capital markets dominated the region. After the crisis, the dominance of the Japanese market has completely disappeared, while the US market remains as a sole dominant player and the Korean market has become more influential.

The Austrian current account deficit: Driven by twin deficits or by intertemporal expenditure allocation?

The evidence presented in the paper rejects the twin deficit hypothesis for the Austrian current account balance during the last two decades. The results are based on an estimate of a vector error correction model including quarterly data for the current account balance and potentially relevant variables driving its dynamics. We compute the variance decomposition of the current account's forecast error and its generalized impulse responses to shocks in the innovations of the system. The results in favor of intertemporal expenditure reallocation cannot be reproduced within a second analysis including the current account and a measure of net output, however. The estimated implicit current account balance, interpreted as the discounted expected change in future net output, does not follow the actual behaviour of the current account.

Ownership relations in the presence of cross-shareholding

The direct ownership structure in a sector can be readily obtained from data on shareholding. Due to cross-shareholding, however, the true ownership structure may be hidden by a complex network of indirect relations. In studying the property structure, two important aspects are the size of the relations between primary owners (e.g. individuals) and secondary owners (e.g. companies), and the distance between them. The distance is obtained from the average number of secondary owners via whom the relation runs. As an empirical application, we study the banking sector in the Czech Republic, where also the relation between distance and separation of dividend and control rights is discussed.      

Monetary policy in Germany: A cointegration analysis on the relevance of interest rate rules

The paper attempts to identify an empirical relationship that characterizes the way the Bundesbank adjusted its short-term rate with respect to various objectives. By building on a careful exploration of the properties of the variables involved, it is established that interest rate rules —often remarkably similar to the Taylor rule— remain valid and relevant in a Vector Error Correction framework, and thereby proposing a distinctive interpretation of German monetary policy during the period 1975–1998.     

服务业对外开放度对产业结构影响的实证分析——基于广东省1990—2008年数据

为了探讨服务业对外开放度对广东产业结构水平的影响,本文基于1990年-2008年时间序列数据建立VAR模型,从服务业的贸易开放与外资开放两个角度分析了广东服务业的对外开放程度,及其与广东产业结构水平之间的动态关系。结果表明,广东产业结构水平的提升主要依赖于自身的发展,相对而言,服务业的外资开放度的促进作用更灵敏且程度更大,且主要通过作用于第三产业来促进广东整体产业结构水平的提升。同时,广东服务业利用外资效率长期低下。增加服务业的外资开放度的同时,提高服务业的外资利用效率为广东产业结构调整战略的重中之选。
