The Difference Between Short and Long Run Effects of Police Outlays on Crime: Policing Deters Criminals Initially, But Later They May 'Learn by Doing'

Abstract . In the long run a positive relationship of police expenditurescrime is derived in models which explain criminal behavior In the short run, however, the statistical results point to the possible deterring effect of police expenditures. A theoretical model is constructed to explain the statistical difference of the short and long run effect of police outlays on crime. As police expenditures increase, crime level diminishes. As time elapses, criminals may adjust to the new level of police effort, improve their performance and at the same level of outlays, increase their criminal activities. This phenomenon could be termed “Criminals’Learning by Doing”. It could explain why, over the long run, the level of crime is positively associated with police expenditures. The empirical analysis examines pooled cross sectional time series of 47 states over the period 1970 to 1980—a total of 517 cases.     

Equity, Price Elasticity, and Household Income Under Increasing Block Rates for Water

Abstract . For an examination of the relationships between household income levels and residential water use, individual household survey data from Tucson, Arizona the combined with monthly water use data for these same households. The objectives were to examine individual response to the existing block rate pricing structure and to provide policy conclusions on potential improvements in this rate structure. A simultaneous equation model of demand is estimated for households within each income group to determine the price elasticity of demand for each income group. The demand models show that under the existing increasing block rate pricing schedules, higher income households not only use more water, but have lower elasticities of demand. Thus a uniform proportional rate increase will cause a larger percentage drop in water use among low income households than among high income households. Given the assumption of declining marginal utility of water use, this result leads to a policy recommendation for substantially steeper block rates to improve interpersonal equity in water pricing.     

Internet Adoption and Advertising Expenditures on Traditional Media: An Empirical Analysis Using a Panel of Countries

The Internet can affect advertising expenditures through various channels. This paper quantifies the relationships between Internet adoption and changes in advertising expenditures on traditional offline media types. I use a panel of 11 years of data at the country level that contains information on advertising expenditures by medium and Internet penetration for more than 80 countries. I find that increases in Internet penetration are negatively correlated with changes in advertising expenditures on newspapers, magazines, and television, but I do not find conclusive results for the correlation between Internet adoption and changes in advertising expenditures on radio.     

Lethal Police Response as a Crime Deterrent:

A bstract . Since Gary Becker's article on the economics of crime and punishment , economists have explored extensively the possible deterrence effect of standard enforcement variables , not only for their public policy implications but to test the hypothesis that illegitimate behavior is sensitive to measures of risk and reward (loss) as well as social, psychological and cultural forces. Research has been needed on the probability of death to the offender caused by official police action—"lethal response." To measure the criminal reaction to intercity variations in the rate of civilian killings of police in the line of duty, a cross-sectional study of 57 cities was undertaken. Variations in non-homicide violent crime rate were found to be inversely related to variations in the intercity lethal response rate. this suggests the presence of a deterrence effect, a one Sixth of one percent decrease in the rate of non-homicide violent crime being associated with a one percent increase in the lethal response rate.     

Crime and Racial Composition in Contiguous Communities as Negative Externalities: Prejudiced Household's Evaluation of Crime Rate and Segregation Nearby Reduces Housing Values and Tax Revenues

Abstract . How the level of amenities in surrounding communities affects the residential location decisions of households is considered. The amenities specifically taken into account are the crime and racial composition of the household's community and the contiguous communities. The theory of the household's valuation of neighborhood amenities through a housing value equation is expanded to include how the household's valuation of amenities is affected by the amenities in surrounding areas. An empirical model using data for 71 suburban communities in the Chicago Standard Metropolitan Statistical Area is specified to measure the simultaneous interaction between housing values, crime, and police effort. A revenue equation is included to determine how the household's valuation of crime and racial composition could affect the community's revenue-raising ability. The empirical results indicate that the crime and racial composition of surrounding communities as well as within the household's community have a statistically significant negative effect on housing values. While the magnitude of the effect is small, the empirical results suggest that households consider the crime rate and racial composition of surrounding communities as negative externalities.     

The deterrence hypothesis revisited

This study explores the causes of crime and the differences in deterrent effects of policing on crimes among rural, suburban, and urban communities. We hypothesize that certain numbers of all crimes are unaffected by policing due to their high net return; policing deters only marginal crimes. That is, unlike other research efforts, we recognize that there is a level of crime indigenous to a given type of community about which little can be done, although a particular community can affect deviations from this level. By introducing this ‘natural rate' of crime we are able to empirically reveal the deterrence effect of police expenditures upon all types of property crimes except robberies. The study analyzes 230 communities in a system of six simultaneous equations, using police, crime, and other socio-economic variables. The model can be used by state and regional policy-makers to more effectively allocate resources to the different types of communities under their jurisdiction and among the various police functions designed to deter specific types of crime.     

Measuring Socioeconomic Effects When Using Income as Quality of Life Indicator

Abstract . By generalizing Stigler and Becker's idea of maintaining the “capital stock intact,” and incorporating it with other contributions to welfare economic analysis, this paper presents a modified conceptual framework for measuring and adjusting impacts of socioeconomic and environmental factors when income or consumption expenditure is used solely as a quality of life indicator. Such measurements and adjustments are made for differences in public needs and in the process of satisfying these needs. Application of this conceptual framework is illustrated, using statistics on police protection and crime rates.     

Economy and Race: Interactive Determinants of Property Crime in the United States, 1958-1995

ABSTRACT Drawing upon rational choice, routine activity, and social disorganization theories, this study investigates changes in rates of property crime known (reported) to police in the United States from 1958 to 1995. Predictor variables include changes in rates of inflation; technological, cyclical, and frictional unemployment; arrest rates for property crimes disaggregated by race (ARPCDR); the interaction of ARPCDR and technological unemployment (to test effects of rising unemployment on whites versus blacks); and a measure of police provisioning. A Beach-MacKinnon Full Maximum-Likelihood FGLS AR1 Method (accompanied by residual analysis) is employed. Significant positive effects are established for (a) inflation, (b) cyclical unemployment, (c) frictional unemployment, and (d) the interaction of white arrest rates and technological unemployment. Police provisioning is not found to be significant. Policy implications are explored along with future policy considerations.     

Analysis of arrest rates for trends in criminality

During the 1960s, the United States experienced a substantial increase in crime with the rates of reported crime more than doubling. It has been postulated that the increase in the proportion of young adults in the population which also occurred during the Sixties is a primary factor in the increase in crime. In this paper, we attempt to explore this question by partitioning the recent increases in rates between an increasing crime-committing propensity for various demographic groups on one hand, and a changing demographic mix to the other. We do this by analyzing arrest rates by demographic group over time. However, since arrest rates are a complex function of both criminality and police activity, a model is developed which attempts to distinguish between these phenomena. The model is estimated using data on age, race, and sex-specific arrest rates for Pittsburgh residents over the period 1967–1972. The results of the analysis suggest that there has been no significant increase in criminality for men in the Pittsburgh population, while there is some evidence of increased criminality for women. However, this increase may reflect an increased willingness of the police to arrest women. We hesitate to generalize our conclusions too widely from the experience of a single urban center. Additional analysis, using the model developed here, of arrest rates from other cities or regions would do much to illuminate this very significant issue.     

Optimal expenditures on police protection

The object of this paper is to propose an approach for operationalizing Rubin's (Minimizing Harm: a New Crime Policy for modern America, Westview Press, Boulder, CO, 1999) idea that minimizing harm is a solution to the crime policy conundrum. Harm is defined to be the total cost of damages due to crime plus the cost of police protection. Its minimization determines optimal expenditures for protection. This is an appropriate basis for specifying the optimal size of a police force, and provides a term of reference for actual policy decisions. Data for the states of the US are used to make the presentation more concrete and to clarify some of the problems that must be solved in actual applications of the method suggested. This does not eliminate the applicability of the approach to any other country or to the geo-political subdivisions within a country. The results obtained are of interest to policy makers dealing specifically with expenditures for police at local, regional or national levels or, more generally, with similar uses of public or private financial resources.     

Is there a compensating wage differential for high crime levels? First evidence from Europe

This paper investigates whether high regional crime levels lead to a compensating wage differential paid by firms in the respective region. Using data from German social-security records, official police statistics and official statistics for 2003–2006, I consider both violent and non-violent crimes and use three-way error-components estimators to control for individual and regional heterogeneity. The findings suggest that wages are practically unrelated to changes in crime rates. This result is robust over a wide range of subgroups. There is, however, some evidence that crime rates influence land prices.     

Applied nonlinear dynamical system in social science. A nonlinear model for social control system: an application to Italian coercion system

Does an increase in police strength discourage an increase in crime levels? It would seem very likely so, despite the many platitudes common everywhere, even in the most serious literature on the subject. This research study, using Non-Linear Analysis on the Italian crime situation from 1985 to 2003, shows an almost non controvertible result. The police force really does seem to have a deterrence function on crime, particularly evident from the 90s on, where, as police strength increases, the number of crimes decrease. One of the most interesting aspects deriving from the non-linear model used, is the specific measurement of the number of crimes that might have been committed and that were not in virtue of the deterrent action of the Police Force. Up to now, such an acquisition seems to be lacking from other so called ‘traditional’ research, where such ‘indirect’ deterrence appears easily hypothesized, but impossible to determine. For this reason too, the adoption of a non-linear analysis logic shows its heuristic superiority able to shed light on certain aspects that in other analysis models would remain in the shadows.     

The Economics of the Criminal Behavior of Young Adults

A bstract This study uses a combination of individual-level and county-level data to estimate an economic model of crime for young adults similar to that used by Becker (1968) and Trumbull (1989). In order to estimate a model of crime in which both individual-level and county-level data are used, it is necessary to take account of the bias introduced by using aggregate-level data in conjunction with individual-level data. In order to eliminate this bias, a technique derived by Moulton (1990) is employed. Results from a logit regression model indicate that race, sex. and peer pressure have statistically significant effects on the probability that a young adult will commit a crime. Results also suggest that police presence, as measured by county-level per capita police expenditures, does not deter young adults from committing crimes.     

Larceny

A dynamic general equilibrium model of larceny - or property crime - is presented in which both economic conditions and government policies affect the commission calculus. The model provides a behavioral framework that is used to estimate the effects of government policies on the commission of larceny. Calibrating the model using data from cities in Los Angeles County, the impact of a number of government policies and of economic development on larceny are quantified. The simulations show that longer prison sentences and higher conviction rates for criminals are the most effective methods to reduce larceny; subsidizing leisure activities, increasing police expenditures and income transfers have little effect on larceny. Using a game-theoretic optimality criterion, all the policies examined are currently overfunded.     

On the dynamics of the Israeli–Arab arms race

This article investigates the causal relationships between the military expenditures and military burden of the four major sides of the Israeli–Arab conflict, namely, Egypt, Israel, Jordan and Syria over the period 1960–2004. We utilize both the causality test suggested by Toda and Yamamoto [Toda, H. Y., & Yamamoto, T. (1995). Statistical inference in vector autoregressions with possibly integrated processes. Journal of Econometrics, 66, 225–250] and the generalized forecast error variance decomposition method of [Pesaran, M. H., & Shin, Y. (1998). Generalized impulse response analysis in linear multivariate models. Economics Letters, 58, 17–29]. Our findings suggest weak causality that runs usually from Israel's to Arab's military spending. The strongest links are between Israel and Syria that are still in a state of enmity. No causality was detected between Israel's and Jordan's military spending.     

Some Determinants of Property Crime: Economic Factors Influence Criminal Behavior But Cannot Completely Explain the Syndrome

Abstract . An empirical analysis of the property crimes, robbery, burglary and larceny, is presented for all 120 counties in Kentucky. While this analysis is based on an economic model of crime, certain sociological and legal variables are included as well in the system of equations. Overall, the empirical results support prior studies’findings with the exception that a quadratic relationship is found to exist between urbanization and each of the property crimes. Furthermore, neither the economic nor the non economic influences measured appear more important for affecting crime rates. Specifically, results indicate that the level of poverty, the degree of tourism, the presence of police, the unemployment rate and the apprehension rate all affect property crimes. In contrast, the length of sentence, the degree of industrialization, the level of public assistance payments and the proportion of youth in the county have no affect on property crime rates in these areas.     

The Effects of Criminal Experience on the Incidence of Crime

A bstract . A hypothesis has been analyzed that criminals learn by doing, that with experience criminals increase their activity so that with level outlays on police the incidence of crime may be increasing. This hypothesis is tested by statistical analysis of time series cross sectional data on crime levels, police outlays and various socioeconomic variables. The results confirm that "learning by doing"—accumulating criminal experience—increases criminal activity, that police outlays have a negative and significant effect on crime and that certain socioeconomic characteristics have a significant effect on crime.     

Employee behavioral options in problematic working conditions: response pattern analysis

This study developed a decision tree framework to predict and distinguish employee responses to problematic working conditions. In this framework, job satisfaction and self-efficacy were antecedent variables; five responses from the modified EVLN typology were used as dependent variables. Data from 367 police officers in Taiwan were analyzed to examine the linear and quadratic relationships between job satisfaction and each of the five responses. The sample was further divided into six groups according to individual job satisfaction and self-efficacy. In each group, specific response patterns were analyzed through paired sample t-tests. The pattern analysis results partially supported the prediction of decision tree framework.     

The Effect of Monopoly Power on National Income, Wage Income and Interest Rates

Abstract . That part of business profits due to monopoly power or other forms of imperfect competition is capitalized into stock prices.Common stock is part of gross wealth, and as such provides a store of value for consumers against emergencies. A very simple graphical model is developed to show how interest rates, gross wealth holdings, and holdings of physical capital are jointly determined. In turn the levels of national income, property income, and wage income are determined once the stock of physical capital and the interest rate are known. In essence, capitalized monopoly profits substitute for physical capital, reducing the economy's stock of capital goods. Similar effects are produced by government debt.     

ESOPs, takeover protection, and corporate decision-making

ESOPs have the potential to align the interests of employees and owners and may increase firm value. However, employee ownership may also strengthen the position of entrenched management. The literature predicts that firms newly protected from takeover threat will tend to (1) increase long-term investment and (2) require additional external monitoring, and/or (3) may use leverage as part of an overall antitakeover strategy. We examined firms that have adopted ESOPs and find that firms raise the level of capital expenditures, research and development expenditures, and dividends. (JEF G320)
