Determinants of household saving: Cointegrated evidence from Pakistan (1975–2011)

The purpose of this study is two-fold: firstly, to analyze the long run relationship between household saving and various socio-economic and demographic variables and secondly, to determine the short run and the long run impact of various socio-economic and demographic variables on the household saving rate in Pakistan. The relationship between household saving and various socio-economic and demographic variables is analyzed by applying Johansen cointegration analysis. Furthermore, Error Correction Model is also estimated in order to find out the convergence of the model towards equilibrium. The results show that there exists a long run relationship between household saving and the variables used in the study, while the result of Error Correction Model reveals that about 45% convergence towards equilibrium takes place every year.     

Economic growth drag in the Central China: evidence from a panel analysis

This article employs recently developed panel methods to test for unit roots, cointegration and Granger causality to justify and estimate the drag induced by resource constraint and environmental pollution for the Central China. The results of the panel cointegration test show that there is a stable long run relationship amongst total output, capital, labour, land, water and SO₂ when total output is the dependent variable. The results of the causality test with Error Correction Model (ECM) analysis suggest that the available water resource and environmental pollutant have no impacts on total output temporarily, but in the long‐run there is a Granger causality running from these variables to total output, indicating the economic growth drag induced by the natural resource and environmental pollution can be further estimated. Given the stable cointegration and significant Granger causality being, the study shows that the drag on the total output reduces annual economic growth rate by about 1.1 percentage points for the Central China as a whole and there is a significant difference on the aggregated and disaggregated drags for the six provinces, which indicates that natural resource and environmental constraints so far incorporated into production probably have a modest effect over the past 31 years for the Central China.     

Demographic Transition and Economic Development in Karnataka

The universal process of population change has significant attainment of social and economic implications at global level. Demographic transition is not only consisting of population growth tendency but much more along with economic consequences Karnataka is in the third stage of demographic transition and this scenario is marked with opportunities and challenges. This paper examines the demographic trends of Karnataka by using different Census data collected from Census reports and time series data over the time period of 1991–2014 collected from SRS. The fertility and mortality levels in the state have declined considerably. The districts in the Karnataka state have shown considerable increment in HDI from decade to decade. The study used the bound testing approach to co-integration; Autoregressive Distributed Lag (ARDL) model was also applied for analyzing the long run relationship whereas Error Correction Mechanism (ECM) was applied for analyzing the short run link of the demographic variables with economic growth. The study exhibited that the demographic transition positively affected the economic growth in the long run and negatively in the short run.

     

Public Expenditure and Revenue in Italy, 1862–1993

This study examines the long‐run equilibrium relationship between government expenditure and revenue in Italy from 1862 to 1993, using cointegration and causality techniques in the long as well as in the short‐run, through integrating the Error Correction Model (ECM) into the traditional Granger causality test. A Granger non‐causality test (due to Toda and Yamamoto) is also performed. Unit root tests have been applied in order to investigate the stationarity properties of the series. Moreover, three more homogeneous sub‐period (1862–1913; 1914–1946; 1947–1993) have been analysed. The nexus between public expenditure and revenue has been discussed also by Forecast Error Variance Decompositions (FEVDs). Empirical findings show that, for each sub‐period, the policy adopted reflects the prevailing paradigm of public finance. In fact, the ‘Tax‐and‐Spend' argument, received empirical support from the liberal period data. In contrast, the interwar years are in line with the ‘Spend‐and‐Tax' hypothesis. Finally, the “Fiscal Synchronization” hypothesis emerges in the republican ages.     

The effect of immigration on unemployment in Europe: Does the core-periphery dualism matter?

The migrant crisis is one of the most challenging tasks the EU has ever faced. This paper uses a Panel Error Correction Model to assess the direction of the impact of immigration on domestic unemployment, in the short and in the long run, for a sample of 15 EU countries between 1997 and 2016. We test for different effects in core and periphery countries based on differences in macroeconomic fundamentals and labor market characteristics. In the long run, immigration is found to reduce unemployment in peripheral countries only, whereas in the short run, we find that immigration reduces unemployment for the whole sample. However, country-specific coefficients based on interactions with labour market characteristics indicate that short-run impacts are larger in Scandinavian and Anglo-Saxon countries. Conversely, Italy, Greece and Portugal show the smallest impacts. Our results suggest that negative sentiments toward immigration due to labour market competition are mostly unjustified.     

国际资本流动对房地产价格的影响——基于中国的实证检验:1998-2006

Taking the inflation into consideration and making use of the quarter data of the actual foreign investment, housing and land prices in China from 1998 to 2006, this paper examines the relationship between housing prices and international capital flows using Error Correction Model (ECM) and Granger causality test. Results show that in the short run, the increase of housing prices attracts the inflow of foreign capitals; in the long run, foreign capitals help to boost the rise of housing prices. Therefore, at present, Chinese government must impose effective restrictions on the flow of foreign capital into the real estate market. __________ Translated from Caijing Wenti Yanjiu 财经问题研究 (Research on Financial and Economic Issues), 2007, (3): 55–61     

Short- and long-run heterogeneous investment dynamics

In this paper, we model the dynamics of business investment taking into account asset-specific characteristics potentially affecting the reactivity of aggregate and disaggregate capital accumulation over the business cycle. We estimate Information and Communication Technologies (ICTs) and traditional investment (non-ICT) determinants within a Vector Error Correction Model testing the assumptions of the flexible accelerator and neoclassical model as well as the role of financial constraints and uncertainty. We evaluate our model on Italian data over the period 1980–2012, and we check our results also with Spanish and UK data. Our findings support the assumption that capital is heterogeneous since short- and long-run determinants are significantly different across the assets. Traditional assets experience stock adjustment costs while ICT investment incurs flow adjustment cost. In the short run, liquidity is a key determinant of investment independently of the asset type. In the long run, uncertainty significantly affects ICT. Finally, the results of the counterfactual exercises support the idea that ICT is a key policy variable to foster economic growth.     

产业结构变动对货币流通速度的影响——中国货币流通速度下降之谜

文章运用协整分析、格兰杰因果检验和误差修正模型实证研究了中国产业结构变动与货币流通速度之间的动态关系以及“货币化假说”。实证分析结果显示货币化对货币流通速度的影响随着时间逐渐增强,但这并不能完全解释我国货币流通速度下降;产业结构变动才是影响我国货币流通速度下降的主要原因。通过误差修正模型发现我国狭义货币流通速度相对于产业结构变动的弹性为2.7,广义货币流通速度相对于产业结构变动的弹性为1.2。     

Do Bank Capital and Liquidity Affect Real Economic Activity in the Long Run? A VECM Analysis for the US

This paper analyses the long‐term economic costs of the new regulatory standards (the so‐called Basel III reform) for the US. Using a Vector Error Correction Model that estimates long‐run relationships among a small set of macro‐variables over the period 1994–2008, it shows that tighter capital and liquidity requirements have negative (but rather limited) effects on the level of long‐run steady‐state output and more sizeable effects on banks’ return on equity. The economic costs are considerably below the estimated positive benefit that the reform should have by reducing the probability of banking crises and the associated banking losses ( BCBS, 2010b ).     

What causes household debt to increase in South Africa?

The 2007–2008 US subprime mortgage crisis evolved into a financial crisis that negatively affected many economies in the world and was afterwards widely referred to as the global financial crisis. Since the beginning of this financial crisis of 2008–2009, South Africa experienced a significant increase in its household debt to income ratio. In the main, this paper investigates the prominent factors contributing to the rise in the level of household debt in South Africa. Specifically, we construct a model for South African household debt through the application of a Vector Error Correction Model (VECM). We employ quarterly time series data throughout the timeline 1985 Q1 to 2012 Q1 and all the econometric tests are analyzed using the statistical software package EViews 7. Our results confirmed the existence of a long run cointegrating relationship between household debt and other macroeconomic determinants. Increasing household debt was found to be significantly affected by positive changes in consumer price index, gross domestic product and household consumption. Also, house prices and household savings were found to positively contribute to a rise in household debt but this relationship was found to be statistically insignificant. Alternatively, household borrowing was found to be significantly and insignificantly affected by negative changes in income and prime rate, respectively. Ultimately, the existence of a long run cointegrated relationship enabled us to build an error correction model for household debt which will facilitate future forecasting.     

Financial deepening,trade openness and economic growth in Latin America and the Caribbean

This contribution investigates the causal interactions between financial deepening, trade openness and economic growth in 13 Latin American and Caribbean countries. We construct a composite indicator for financial deepening and use it to detect Granger causality within a modified Vector Autoregressive/Vector Error Correction Model (VAR/VECM) framework. We find almost no evidence for the popular hypothesis of finance-led growth. Evidence of bidirectional finance–growth causality is stronger but mostly instable in the long run. Most results indicate a demand following or insignificant causal relationship between finance and growth. There is also no evidence that finance indirectly induces growth via the channel of trade openness. Hence, policies that prioritize financial and trade sector development cannot be supported.     

Exploring determinants of housing prices: A case study of Chinese experience in 1999–2010

How do macroeconomic variables affect housing prices? In this paper we apply a non-linear modeling approach, the Nonlinear Auto Regressive Moving Average with eXogenous inputs (NARMAX), to investigate determinants of housing prices in China over the period 1999:01 to 2010:06. The NARMAX approach, combined with the famous Vector Error Correction Model (VECM), has an advantage over prevailing methods in that it automatically selects linear and non-linear forms of variables and the numbers of corresponding lags according to statistical properties. Estimation results mainly identify some key monetary and price variables in interpreting housing price dynamics, including most notably mortgage rate, producer price, broad money supply and real effective exchange rate. Meanwhile, real economic variables such as income are not independently significant.     

Monetary shocks,exchange rates and trade balances: Evidence from inflation targeting countries

This paper investigates the relationship among monetary policy shocks, exchange rates and trade balances in five Inflation Targeting Countries (ITCs). The investigation is based on Structural Vector Error Correction Models (SVECMs) with long run and short run restrictions. The findings reveal that a contractionary monetary policy shock leads to a decrease in price level, a decrease in output, an appreciation in exchange rate, and an improvement in trade balance in the very short run. Our findings contradict the findings of price, output, exchange rate and trade puzzles that have been found in many empirical studies. Furthermore they are consistent with the theoretical expectations regarding the effect of a contractionary policy. The only long run restriction that we imposed on our models is that money does not affect real macroeconomic variables in the long run, which is consistent with both Keynesian and monetarist approaches.     

Money Demand and Purchasing Power Parity (PPP), in the Republic of South Africa

We have examined empirically two important economic relationships, the Purchasing Power Parity (PPP) and the money demand relationship, among the consumer prices, money, output, interest rates, and the nominal rand/dollar exchange rate of the Republic of South Africa (RSA) for the sample period from 1993 second quarter to 2003 second quarter within the frameworks of co-integration and Error Correction Model (ECM). It is established that the strong version of the PPP including the proportionality and the symmetry hypothesis, is supported. The changes in the rand/dollar exchange rates are influenced by the long term trends in the consumer prices of the RSA and the USA. There also exists a well defined money demand function for this period. The broad money demand is influenced by the consumer prices, the GDP and the interest rates. The short-term interest rates are found to be the own rate of return for broad money and the long-term bond yield is the opportunity cost of holding money. The monetary policy works through the short term interest rates.

Migration and labour markets in OECD countries: a panel cointegration approach

This article examines the interaction between immigration and the host labour market of 14 Organization for Economic Co-operation and Development (OECD) countries using nonstationary panel data methodology. We estimate a trivariate Vector Error Correction Model (VECM) and derive causality tests to simultaneously assess the long- and short-term macroeconomic impact of newcomers on wages and unemployment levels in the host country. The results suggest that an increase of migrants is likely to increase wages in the destination countries in the short run but to increase them in the long run. There is no evidence of adverse effects on unemployment due to immigration in short and long-term except for Anglo-Saxon countries in the short term. Our findings also show that immigration is conditioned by levels of unemployment and wages especially in Anglo-Saxon countries.     

Linkages between inflation,economic growth and terrorism in Pakistan

This paper investigates the linkages between inflation, economic growth and terrorism using annual frequency data over the period of 1971–2010, the maximum time period for which consistent data is available for Pakistan. The ARDL bounds testing approach to cointegration has been applied while robustness of long run relationship is established by using rolling window approach. The empirical evidence confirms the cointegration between inflation, economic growth and terrorism in Pakistan. An increase in inflation raises terrorist attacks while economic growth is also a major contributor to terrorism. Moreover, bidirectional causality is found between inflation and terrorism as investigated by the VECM Granger-causality approach while variance decomposition approach also supports the findings by the VECM Granger causality analysis. Our results therefore points to benefits of pursuing sustainability of low inflation in reducing terrorism. However, it also implies some difficulties for policy-makers in Pakistan in their pursuit for economic growth as latter would result in an increase in terrorism activities crowding out some of the benefits of economic growth.

An error correction model of induced innovation in UK agriculture

Cointegration techniques are applied to a model of induced innovation based on the two-stage Constant Elasticity of Substitution (CES) production function. This approach results in direct tests of the inducement hypothesis, which are applied to agricultural data for the United Kingdom from 1953 to 2000. The time series properties of the variables are checked, cointegration is established and an Error Correction Model (ECM) constructed, which attempts to separate factor substitution from technological change. Finally, the ECM formulation is subjected to causality tests, which show that the factor price ratio for chemicals and land is Granger-prior to the factor-saving bias of technological change. However, long-run relative prices are not causally prior to the machinery/labour ratio. This results from perturbations in the user cost of machinery, caused by oil price shocks. Thus, the Induced Innovation Hypothesis (IIH) may explain long-run transformations like the mechanical and fertilizer revolutions that dominated the twentieth century, but not reflect short-run price volatility.     

THE MONEY DEMAND FUNCTION FOR THE EURO AREA: SOME EMPIRICAL EVIDENCE

This paper sets out to re‐examine the money demand function for the euro area. Traditional specifications often yield unsatisfactory results: instability of short and long‐term coefficients; relatively large differences between estimated and actual value of variables; and significant changes in the number of long‐term relationships, etc. Using a standard Vector Error Correction Model, we find that the usual specification is indeed unstable. However, introducing a European equity price gives rise to a more stable system. Furthermore, recursive estimates confirm the relative stability of long‐term coefficients. Estimates of the real money gap, based on the money demand equation including equity prices, point to moderate, albeit persistent, excess liquidity in the euro area in recent years. The real money gap contains information about future inflation but this content may have diminished since 2001.
