Detecting cointegration relationships under nonlinear models: Monte Carlo analysis and some applications

Testing for cointegration in the presence of nonlinear adjustments or structural breaks is important for examining the equilibrium relationship among economic variables. It is known that standard cointegration tests perform poorly when a cointegration relationship has nonlinear adjustments or structural breaks. However, it is not clear how some cointegration tests allowing for nonlinearity perform under other classes of nonlinear cointegration models. This paper investigates which cointegration tests help detect a cointegration relationship with nonlinear adjustments or structural breaks. Our Monte Carlo simulation results demonstrate that the cointegration test with threshold adjustment generally has better power performance under most cointegration relationships with nonlinearity. We also provide empirical applications to the money demand and term structure of the U.S. interest rates. The empirical results show that the test allowing for threshold adjustment provides strong evidence of the cointegration relationships of money demand and the term structure of interest rates.     

The effects of unemployment benefits on U. S. Unemployment rates

Zusammenfassung Die Auswirkungen der Arbeitslosenunterstützung auf die Erwerbslosenquote in den Vereinigten Staaten. —In diesem Aufsatz wird an einem preistheoretischen Modell untersucht, wie die Verfügbarkeit von Arbeitslosenunterstützung die Freizeit-Lohn-Konstellation für den ?Durchschnittsarbeiter? ver?ndert und geeignet ist, Arbeitslosigkeit zu verursachen. Anhand des Modells wird gezeigt, wie marktm?\ige und institutionelle Sicherungen in den Versicherungsprogrammen —wie die Notwendigkeit, eine neue Arbeit zu finden, das Bestehen einer Wartezeit vor dem Empfang der Versicherungsleistungen und die Anforderungen für das Erfüllen der Anspruchsvoraussetzungen —den Anreiz zur Arbeitslosigkeit, der durch Versicherungszahlungen ausgel?st wird, vermindern. Das theoretische Modell führt zu einer Spezifizierung von Sch?tzgleichungen. Es werden aggregierte Zeitreihen-Daten der Vereinigten Staaten für 1951–1972 und ein Querschnitt von U.S.-Bundesstaaten für 1971 benutzt. Dabei ergibt sich, da\ die unabh?ngigen Variablen, die als Determinanten induzierter und zyklischer Arbeitslosigkeit unter den Versicherten vermutet wurden, theoretisch erwartete Vorzeichen und statistisch signifikante Koeffizienten haben. Das wichtigste Ergebnis der empirischen Untersuchung ist, da\ —h?tte 1972 das Verh?ltnis von Unterstützungszahlungen und Lohnh?he, der Anteil der versicherten Arbeitskr?fte und die Beachtung der Anspruchsvoraussetzungen den Verh?ltnissen im ?Vollbesch?ftigungsjahr? 1955 entsprochen —die Arbeitslosenquote in den Vereinigten Staaten ceteris paribus 5,0 vH statt 5,6 vH betragen h?tte, d. h. sie w?re um etwa 11 vH niedriger gewesen. Ein ?hnliches Resultat wurde bei einer Querschnittsregression für die 48 U.S.-Bundesstaaten erzielt. Die Autoren folgern daraus, da\ diese Ergebnisse es noch dringlicher machen, die ?ffentliche Debatte über ein zweckm?\iges Vollbesch?ftigungsziel für die Geld- und Fiskalpolitik der Vereinigten Staaten wiederaufzunehmen und Fragen hinsichtlich der optimalen H?he der Unterstützungszahlungen und der Beachtung der Anspruchsvoraussetzungen zu stellen.

Résumé Les effets des bénéfices de ch?mage sur les taux de ch?mage des E.U. —Dans cet article nous développons un modèle de prix théorique qui montre comment la disponibilité des bénéfices d’assurance de ch?mage change la position d’opportunité de revenu vis-à-vis des loisirs avec laquelle on confronte un ouvrier ?moyen? et comment elle a une tendance à stimuler le ch?mage. Nous utilisons le modèle de montrer comment les sauvegardes de marché aussi bien que les sauvegardes institutionelles dans les programmes d’assurance par exemple la nécessité de trouver un nouveau travail, l’existence les périodes d’attente avant de recevoir les bénéfices aussi bien que les co?ts de se soumettre aux règles d’éligibilité reduisent les incitations de ch?mage créées par les paiements de bénéfice. Le modèle théorique nous conduit à la spécification des équations d’estimation. En utilisant les données agrégées des séries de temps d’E.U. de 1951–1972 et une section transversale des états d’ E.U. en 1971 nous trouvons des signes attendus théoriquement et des coefficients statistiquement signifiants des variables indépendantes desquelles nous avons supposé qu’elles sont les variables déterminantes du ch?mage stimulé et cyclique parmi les assurés. Le résultat le plus important de notre étude empirique est que si en 1972 les bénéfices d’assurance de ch?mage relatifs aux salaires, la couverture des ouvriers et le renforcement des règles d’éligibilité auraient été au niveau de 1955, une année de ?plein emploi?, puis le taux de ch?mage d’E.U. ceteris paribus aurait été plut?t 5,0 vis-à-vis le pourcentage actuel de 5,6 ou environ 11 pourcent plus bas. Nous avons obtenu un résultat similaire avec une régression de section transversale des 48 états d’E.U. voisins. Nous conclusons que ces résultats renforcent l’urgence de réouvrir le débat public concernant le but de plein emploi approprié pour les politiques monétaires et fiscales d’E.U. et laissent élever les questions sur les paiements optimum de bénéfice de ch?mage et sur le renforcement des règles d’éligibilité.

Resumen Los efectos de los beneficios por desempleo sobre las tasas de desempleo en los EEUU. —En este artículo desarrollamos un modelo de teoría de precios que muestra que la disponibilidad de beneficios de seguros de desempleo produce un cambio en la relación de oportunidad entre ocio e ingreso para un trabajador ?promedio? y tiende a inducir desempleo. Se usa el modelo para mostrar cómo el mercado y las garantias institucionales de los programas de seguros, tales como la necesidad de encontrar un nuevo trabajo, la existencia de períodos de espera antes de recibir beneficios y el costo de someterse a las reglas reducen los incentivos en favor de desempleo creados por el pago de beneficios. El modelo teórico lleva a la especificación de ecuaciones estimativas. Usando datos para series de tiempo agregadas de EEUU en el período 1951–1972 y una estimación de sección transversal de los estados norteamericanos en el a?o 1971, encontramos signos teóricamente esperados y coeficientes estadísticamente significativos para las variables independientes, las que hipotéticamente son las determinantes del desempleo inducido y cíclico entre los asegurados. El resultado más importante de nuestro estudio empírico es que si en el a?o 1972 los beneficios del seguro de desempleo en relación a los salarios, la cobertura de trabajadores y la imposition de reglas de aceptación hubieran permanecido en el nivel de 1955, un a?o de ?pleno empleo?, entonces la tasa de desempleo norteamericana, ceteris paribus, hubiera sido 5.0 p.c. en vez de 5.6 p.c., o alrededor de 11 p.c. más baja. Un resultado similar fue obtenido de una regresión de sección transversal de 48 estados norteamericanos contiguos. Concluimos que estos resultados agregan una urgencia adicional a la reapertura de un debate público sobre una meta apropiada de pleno empleo para las políticas monetaria y fiscal de los EEUU y levantan preguntas sobre pagos óptimos de beneficios por desempleo y la imposición de reglas de aceptación.

     

Policy Uncertainty and the Demand for Money in Korea: An Asymmetry Analysis

Previous studies included money supply volatility as well as output volatility as measures of uncertainty in estimating the demand for money. However, a more comprehensive measure of uncertainty is now constructed for many countries and is known as policy uncertainty. When we included this new measure in the formulation of the demand for money in Korea and relied upon a nonlinear specification of the money demand which allows us to assess the asymmetric effects of changes in the policy uncertainty measure, we found asymmetric long-run effects of policy uncertainty on the demand for cash in Korea. Our conjecture is that increased uncertainty induces Koreans to hold less cash in favor of safer assets and decreased uncertainty has opposite effects, though at different rate.     

An evaluation of the 1977 Canadian firearm legislation: robbery involving a firearm

The effect of the 1977 Canadian firearm legislation on robberies involving firearms is evaluated between 1974 and 1992 using a pooled cross-section, time series model. The results show that the 1977 legislation did not reduce robbery involving firearms, nor did it have a significant effect on the total robbery or armed robbery rates. The legislation may even have acted perversely in that it may have increased robberies with firearms. In general, these results are consistent with previous published findings but contrast with unpublished governmental studies. The implication that this legislation may have acted perversely is new and requires further investigation.     

The equilibrium relationship among money,income, prices,and interest rates: evidence from a threshold cointegration test

The long-run equilibrium relationship among money, income, prices, and interest rates in Japan is investigated by the threshold cointegration test, which allows for asymmetric adjustment, introduced by Enders and Siklos (2001 Enders, W and Siklos, PL. 2001. Cointegration and threshold adjustment. Journal of Business and Economic Statistics, 19: 166–76. [Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]). The threshold cointegration approach provides clear evidence of the cointegration relationship characterized by asymmetric adjustment. By allowing for asymmetric adjustment, results are obtained showing the stability of the money demand function, similar to Lucas (1988 Lucas, RW Jr. 1988. Money demand in the United States: a quantitative review. Carnegie-Rochester Conference Series on Public Policy, 29: 137–68.  [Google Scholar]), who pointed out that the money demand function is stable if unit income elasticity is imposed. In particular, the estimated results show that the adjustment process toward equilibrium is highly persistent above an appropriately estimated threshold, whereas the adjustment process toward equilibrium quickly converges below it. This finding indicates that deviations from equilibrium resulting from increases in money or decreases in income and prices are highly persistent.     

Explaining regional variation in business births and deaths: U.S. 1976–88

Linear models are developed to determine the relative impact of 15 start-up processes on the annual regional birth rate of new business organizations for all industry sectors in the U.S. over 6 two-year periods. These stable linear models explained from 50–70|X% of the variation in regional firm birth and death rates up to 16 years into the future. Start-up processes that have the most impact involve regional economic diversity; population growth; greater personal wealth; presence of mid-career adults; low unemployment; and greater flexibility in employment relationships. There was a complete absence of any impact of regional variation associated with higher densities of customers, suppliers, workers, R&;D resources; costs of production; or access to national transportation facilities.     

Lending attitude as a financial accelerator in a credit network economy

In existing literature, commercial banks are often considered mere financial intermediaries that facilitate the flow of credit in an imperfect credit market. However, as demonstrated in the history of financial instability, the behavior of financial institutions plays an important role. This paper examines how lenders’ attitudes affect macroeconomic performance. In our analysis, the economy is composed of multiple borrowers (firms) and one lender (bank). Each borrower is directly connected to the lender through its credit contract. At the same time, each borrower is indirectly connected to all the other borrowers within the credit network. Using this model, we execute computer simulations to examine the economic consequences of lending attitudes. The results of the simulations demonstrate that the bank’s lending attitude functions as a financial accelerator; that is, it significantly affects the dynamics of the economic system through the credit network. Consequently, the same level of exogenous shock generates completely different outcomes depending on the different lending attitudes. The results also show that there exists an optimal lending attitude that leads to high economic growth and a stable growth path.     

Human resource management in the Canadian manufacturing sector

Using a sample of 356 Canadian manufacturing organizations, this study examines the pattern of implementation of a wide range of HRM practices including external recruitment procedures, internal job posting systems, performance appraisal methods, job evaluation methods and pay-for-performance systems. A comparison of the adopted HRM practices between large and small firms and between union and non-union firms is also made. The results show that the main difference between large and small firms lies in the recruitment procedure and the job evaluation process. The difference between the union and non-union firms is associated with the greater emphasis placed on performance by the latter.

This study also presents some evidence regarding the perceived importance of twenty HRM activities. The evidence suggests that the three most important activities include health and safety compliance, employee/labour relations and disciplinary issues. On the other hand, the three least important ones are conducting attitudinal surveys, public relations activities and career planning development.
