Modeling crime in Japan

This study aims at identifying the factors of aggregate and disaggregate crime categories in Japan over the period 1964–2009. All crime categories are related to police outlays, police numbers, unemployment, divorce and urbanization rates. Bounds testing approach to cointegration is implemented to test the existence of a long-run relationship amongst the variables. Cointegration analysis yields that the main deterrent effect on crime is the police presence and this factor is further confirmed by the real police outlays. As for the essential cause of crime, urbanization stands as the leading factor which is followed by divorce and unemployment rates. Policy implications are discussed.     

Financial reforms and credit growth in Nigeria: empirical insights from ARDL and ECM techniques

In the last 37 years, Nigeria has undergone several stages of financial reforms with different impacts on the economy. This paper analyses the impact of these financial reforms on credit growth in Nigeria using annual data from 1980 to 2016. The research work hinges on the theoretical underpinning of McKinnon-Shaw hypothesis on the relevance of financial reforms in a lagging economy. Analysing the data with autoregressive distributed lag error correction representation and bounds testing techniques, we find evidence supporting this hypothesis, and specifically that at higher real interest rates there is increased financial intermediation evidenced by credit growth. Other findings are that in the long-run, financial system deposits, inflation rate and per capita GDP are strong asymmetrical predictors of credit growth and real interest rates (the financial reform indicator), while the short-run relationships are indicator-specific. We further show that a long-run cointegration relationship exists between domestic credit and other covariates and likewise between the real interest rate and its regressors.     

Inequality and criminality revisited: further evidence from Brazil

The objective of this study is to shed light on the determinants of criminality rates in Brazil. A panel data model was estimated using Brazilian states’ data. Our main result suggests that income inequality plays an important role in the determination of the crime rate. Furthermore, there are evidence suggesting that both unemployment and urbanization rates are positively related to crime. Based on a GMM approach we find the existence of an “inertial effect” on criminality. Besides that, the GMM results show that public security spending is effective in reducing criminality rates. Contrary to the common wisdom, we could not find evidence that poverty increases violent crimes. Finally, we have evidence that income inequality Granger causes crime, but not the reverse.     

A Time Series Analysis of the Relationship between Inflation Uncertainty and Unemployment

This paper examines the empirical relationship between inflation uncertainty and unemployment rates. We find supportive evidence of a significant positive association between inflation uncertainty and unemployment, but this relationship depends critically on three factors. First, the inflation uncertainty-unemployment relationship is not significant before the mid-1970s. Second, the inflation uncertainty-unemployment relationship does not hold across all single digit SIC industries. And third, the inflation uncertainty-unemployment relationship is concentrated at business cycle and long-run components of the data, rather than high-frequency components.     

The long-run Phillips curve and non-stationary inflation

Modern theories of inflation incorporate a vertical long-run Phillips curve and are usually estimated using techniques that ignore the non-stationary behaviour of inflation. Consequently, the estimates obtained are imprecise and unable to test the veracity of a vertical long-run Phillips curve. We estimate a Phillips curve model taking into account the non-stationary properties in inflation and identify a small but significant positive relationship between inflation and unemployment. The results also provide some evidence that the trade-off between inflation and the rate of unemployment in the short-run worsens as the mean rate of inflation increases.     

REVISITING THE REAL WAGES–UNEMPLOYMENT RELATIONSHIP. NEW RESULTS FROM NON-LINEAR MODELS

We examine the long-run real wages–unemployment relationship for five OECD countries over the period 1960:1–2001:4. Given the theoretical possibility of non-linear equilibrium due to downward real wage rigidity we employ econometric tests that allow for the presence of non-linearities in the long-run equilibrium. We adopt the notion of 'hidden co-integration' suggested by Granger and Yoon . This methodology has several advantages with respect to other non-linear models. We find statistical evidence that, in general, there is a long-run positive relation between real wages and unemployment only when both are affected by positive shocks. We also find a negative relationship between unemployment and productivity. The empirical analysis is complemented with the estimation of error correction models for all countries.     

Impact of exchange rate uncertainty on commodity trade between US and Sweden

Previous studies that investigated the effects of exchange rate uncertainty on the trade flows of Sweden employed aggregate trade data either between Sweden and the rest of the world or at bilateral level between Sweden and her major trading partners. In this article, we disaggregate the trade data and employ the import and export data from 87 industries that trade between Sweden and the US. We find that exchange rate volatility has significant short-run effects on the trade flows between the two countries in almost two-third of the industries. However, the short-run effects are translated into the long-run effects in one-third of the cases. Furthermore, the real depreciation of krona against the dollar was found to have favourable effects on the overall trade balance between the two countries.     

Search for a theory of organized crimes

Casual empirical observations reveal no systematic relationship between the overall crime rate and organized criminal activity. We develop a search-theoretic framework to study the interactions not only between formal labor and crime sectors but also between individual and organized crimes. In equilibrium, individual and organized criminals face different arrest risks, success rates, reward structures and outside options. We characterize agents' “occupational choices,” the gang's hierarchical structure and the responses of unemployment, crime rates and crime composition to changes in labor-market conditions and crime-deterrence policies. We further assess the effectiveness of arrest versus punishment policies in deterring individual and organized crimes.     

Commodity trade between Pakistan and the US: is there evidence of the J-curve?

A few studies that have attempted to estimate the short-run (J-curve) and long-run impact of exchange rate depreciation on Pakistan’s trade balance are either based on aggregate trade data between Pakistan and the rest of the world or between Pakistan and her bilateral trading partners. The findings are mixed at best. Considering the trade balance between Pakistan and the US, as one of its major partners, no significant effects have been discovered. Suspecting that the trade flows between the two countries could suffer from another aggregation bias, we disaggregate their trade flows by commodity and consider the trade balance of 45 industries that trade between the two countries. We find significant short-run effects of currency depreciation on the trade balance of 17 industries. The short-run effects last into the long run in 15 cases. The largest industry that account for more than 10% of the trade seems to benefit from real depreciation in the long run.     

Unemployment and Crime: Is There a Connection?

A panel of Swedish counties over the years 1988–1999 is used to study the effects of unemployment on property crime rates. The period under study is characterized by turbulence in the labor market—the variation in unemployment rates was unprecedented in the latter part of the century. Hence, the data provide a unique opportunity to examine unemployment effects. According to the theory of economics of crime, increased unemployment rates lead to higher property crime rates. A fixed‐effects model is estimated to investigate this hypothesis. The model includes time‐ and county‐specific effects and a number of economic and socio‐demographic variables to control for unobservables and covariates. The results show that unemployment had a positive and significant effect on some property crimes (burglary, car theft and bike theft).     

Long-run waves or short-run fluctuations – what establishes the correlation between oil and food prices?

The strong correlation between food prices and energy prices has gained much attention in the public debate. In this article, we focus on the so-called excess co-movement, which is the correlation between crude oil price and the prices of food commodities after controlling for economic activity. We use a frequency domain Granger causality test to analyse short-run and long-run relationships between crude oil prices and prices of food commodities. For important biofuel inputs like maize, soybeans, rapeseed and EU sugar, we find evidence for long-run Granger causality in particular for the period after 2007. This supports the hypothesis that the increasing biofuel production creates the link between the prices of crude oil and food commodities. However, we also find short-run Granger causality for various food commodities. This result is more in line with herd behaviour or speculation in commodity markets.     

Explaining House Prices in Australia: 1970–2003*

This paper aims to explain changes in real house prices in Australia from 1970 to 2003. We develop and estimate a long-run equilibrium model that shows the real long-run economic determinants of house prices and a short-run asymmetric error correction model to represent house price changes in the short run. We find that, in the long run, real house prices are determined significantly and positively by real disposable income and the consumer price index. They are also determined significantly and negatively by the unemployment rate, real mortgage rates, equity prices and the housing stock. Employing our short-run asymmetric error correction model, we find that there are significant lags in adjustment to equilibrium. When real house prices are rising at more than 2 per cent per annum, the housing market adjusts to equilibrium in approximately four quarters. When real house prices are static or falling, the adjustment process takes six quarters.     

What determines households inflation expectations? Theory and evidence from a household survey

The purpose of the present paper is to study how households form inflation expectations using a novel survey dataset of Italian households. We extend the existing ‘inattentiveness’ literature by incorporating explicitly inflation targets and distinguishing between aggregate and disaggregate dynamics based on demographic groups. We also consider both the short- and long-run dynamics as households update their inflation expectations. While we find clear distinctions between the various demographic groups behavior, households tend to absorb professionals forecast. The short-run dynamics also indicate they not only overreact when updating their expectations but also adjust asymmetrically to any perceived momentum change of future inflation.     

Crime and benefit sanctions

In this paper we look at the relationship between crime and economic incentives in a different way to other work in the economics of crime field. We look at empirical models where a toughening of the unemployment benefit regime can be used to study how people on the margins of crime may react to changes in economic incentives. We present three sets of complementary evidence, all of which show that toughening the benefit regime can have an unintended consequence, namely increases in crime. The first approach presents quasi-experimental evidence, looking at crime rates in areas of England and Wales before and after the introduction of a new, tougher unemployment benefit programme—the Jobseekers Allowance (JSA)—in October 1996. The second approach considers qualitative evidence on individuals affected by the change in the benefit regime. The third relates changes in area crime rates to post-JSA sanctions. Each of these approaches uncovers evidence of higher crime occurring as a consequence of the benefit reform.

Insurance development,banking activities,and regional output: evidence from China

This paper applies panel cointegration tests and panel vector error correction models to investigate the interrelationship among the banking sector, insurance market, and regional output based on the samples from 25 Chinese provinces. We first find that there is a fairly strong long-run cointegrating relationship among real GDP, banking credit, and real insurance premiums. Second, both insurance markets (life and non-life) and the banking sector have a positive effect on real output. Third, we determine that banking activities and economic growth exhibit long-run and short-run bidirectional causalities. Fourth, there is fairly strong evidence in favor of the hypothesis for the long-run bidirectional causal relationships between insurance premiums and economic growth, taking into account the critical channel of the banking sector. Finally, we provide some beneficial suggestions for investors and policy-makers.     

Determinants of violent and property crimes in England and Wales: a panel data analysis

We examine various determinants of property and violent crimes by using police force area level (PFA) data on England and Wales over the period of 1992–2008. Our list of potential determinants includes two law enforcement variables namely crime-specific detection rate and prison population, and various socio-economic variables such as unemployment rate, real earnings, proportion of young people and the Gini Coefficient. By adopting a fixed effect dynamic GMM estimation methodology we attempt to address the potential bias that arises from the presence of time-invariant unobserved characteristics of a PFA and the endogeneity of several regressors. There is a significant positive effect of own-lagged crime rate. The own-lagged effect is stronger for property crime, on an average, than violent crime. We find that, on an average, higher detection rate and prison population leads to lower property and violent crimes. This is robust to various specifications. However, socio-economic variables with the exception of real earnings play a limited role in explaining different crime types.     

Wealth effects on the housing markets: Do market liquidity and market states matter?

This paper analyzes the effect of household wealth (including housing and financial wealth) on housing sales and probes their long-run and short-run dynamic relationships. We further examine the short-run effect of financial wealth on housing sales by employing quantile regressions, restricted upon different liquidity (quantile) levels and up-down housing markets, from which the differences between the early and late stages of an uptrend/downtrend can be respectively exhibited. We find that housing wealth, income, and mortgage rates have long-run influences on housing sales. Looking at the short run, we find that housing sales only respond to housing wealth and mortgage rates. When we distinguish the effects of financial wealth on housing sales in up-down housing markets, we note a positive influence of financial wealth on housing sales in down markets, but not in up markets. Particularly, our results show an impact of housing liquidity on the short-run relationships.     

Asymmetric behavior of Australia's Big-4 banks in the mortgage market

This paper presents an alternative framework for modeling the behavior of banks in setting lending and/or saving rates. In a short-run dynamic model, we correct for deviations from the long-run path using three feedback coefficients capturing different disequilibria. This enables us to test for both amount and adjustment asymmetries by considering the size and direction of any deviations. We use this model to examine the relationship between the official cash rate (set by the Reserve Bank of Australia as a monetary policy tool) and the standard variable mortgage rates of Australian Big-4 banks using weekly data from 2001 to 2012. The evidence indicates both types of asymmetries along with synchronized rate-setting behavior. Overall, the banks immediately pass on 120% of any rate rise, but only 85% of any rate cut. Further, when mortgage rates are substantially above the equilibrium path, we find no significant attempt to lower rates, but faster adjustment when rates are below equilibrium values. This finding has important implications for the RBA's monetary policy transmission mechanism and the effectiveness of the expansionary versus contractionary policy.     

Remittances and the real effective exchange rate

We examine the long-run relationship between remittances and the real exchange rate for less-developed countries. In a key departure from the literature, we employ a panel cointegration approach using an innovative method for the measurement of the multilateral real effective exchange rate and we focus on high-remittance economies. We find a small inelastic, but significant, long-run relationship which confirms a Dutch disease type effect. The short-run relationship is explored using a panel vector error correction model which confirms that short-run causality is unidirectional running from remittances to the exchange rate. Potential asymmetries in this relationship are identified using quantile regression analysis.     

Aggregate price responses to wage and productivity changes: Evidence from the U.S.

This papei examines the dynamic responses of prices to wage and productivity changes and distinguishes between short-run and long-run effects. The long-run solution of the dynamic specification is consistent with the hypothesis of markup pricing over unit labour costs. The restrictions implied by this long-run behaviour are not rejected.by U.S. data. In addition, the evidence supports the view that the short-run wage effects are significantly stronger than productivity effects.
