This paper calculates the NAIRU for the US in a framework that allows inflation and unemployment to be jointly endogenous.
We define the NAIRU as being the component of actual unemployment that is uncorrelated with inflation in the long run. We
use a structural VAR to estimate the NAIRU and core inflation simultaneously and with greater precision than most of the previous
literature. Our results show that the NAIRU fell dramatically at the end of the 1990s from 6.7% before 1997 to 5.2% afterwards. 相似文献

We use a data-rich approach, a factor-augmented vector autoregression (FAVAR), to identify idiosyncratic exchange rate shocks and examine the effects of these shocks on different sectors of the New Zealand economy. We find that an unexpected shock to the exchange rate has significant effects on relatively tradable sectors of the economy. Whilst this is expected, relatively ‘more’ non-tradable sectors of the economy are also influenced by shocks to the exchange rate, presumably due to their linkages to more trade-exposed sectors. We also find that exchange rate shocks explain a small proportion of overall business cycle variability, implying that the exchange rate acts as a buffer rather than as a source of shock. 相似文献

The impact of government debt on the long-run natural real interest rate – a quantitative evaluation
Christoph Winter 《Applied economics letters》2017,24(20):1429-1434
Persistently low natural real interest rates are a problem for monetary policy and financial stability. I analyse to what extent a permanent increase in government debt that is financed by higher taxes could raise the long-run natural real interest rate. As a measurement tool, I use an incomplete markets model with capital and government bonds. Increasing the public debt/GDP ratio by one percentage point raises the real interest rate by between 0.4 and 1.5 basis points, depending on the degree of inequality generated by the model and the tax instrument used to balance the government’s budget constraint. I also show that the interest rate effect of a change in public debt/GDP predicted by the model is significantly smaller than its empirical counterpart for the US, due to the fact that the model understates the empirical fraction of households that are constrained in their consumption decision. 相似文献

This article analyzes the impact of monetary policy during periods of low and high financial stress in the US economy using a threshold vector autoregression model. There is evidence that expansionary monetary policy is effective during periods of high financial stress with larger responses having a higher proportionate effect on output. The existence of a cost channel effect during periods of high financial stress implies the existence of a short run output-inflation trade off during financial crises. Large expansionary monetary shocks also increase the likelihood of moving the economy out of a high financial stress regime. 相似文献

The cause of Danish unemployment: Demand or supply shocks? 总被引:1,自引:1,他引:0
We study the Danish unemployment experience 1905–92 using a common trends model with cointegration constraints. To justify
the identifying assumptions about the cointegration vectors and the common trends we present a simple macroeconomic model
of the labor market. The model determines the long run behavior of labor productivity, employment, unemployment, real product
and real consumer wages. The empirical results give support for three cointegration relations and two common trends. Based
on the economic model the trends are interpreted as representing labor productivity (technology) and labor supply. With unemployment
being nonstationary, the common trends analysis indicates that labor supply shocks is the primary source for explaining the
behavior of unemployment.

The goal of the present article was to investigate not only the dynamics of the Greek public debt, but also the appropriate measures required for achieving fiscal consolidation. The empirical estimation is carried out using a macroeconomic data set spanning the period 1980–2008 and both the three-stage least squares (3SLS) methodological approach on a theoretical model and the structural VAR methodology to perform forecast tests and to calibrate the future paths of the public debt variable up to 2020. The results suggest that only a restrictive fiscal policy that simultaneously increases government revenues and reduces government expenditure could permit the country to achieve debt sustainability. The results also suggest that debt sustainability can be achieved faster when tax revenue policies are intensified. The results are expected to have important implications to policymakers for designing effective macroeconomic policy in terms of achieving sustainable levels of public debt. 相似文献

The purpose of this article is to quantify the employment effects of the recent German welfare reform. The key element of this reform was to merge the coexisting transfer systems Social Assistance (SA) and Unemployment Assistance (UA) into one unified benefit (Arbeitslosengeld II – ALG II). We also consider a second reform scenario that is intended to further improve the labour supply incentives of low-skilled workers. Our methodological contribution is to use an integrated CGE-microsimulation model. In adopting such an approach, we are able to combine the advantages of microsimulation studies by accounting for the large amount of heterogeneity in terms of households’ preferences and budget constraints with the advantages of an applied general equilibrium model. The latter permits us to identify potential general equilibrium repercussions through changes in wages and unemployment. The simulations indicate that the introduction of ALG II results in a negligible increase in employment of only 45?000 individuals. In contrast, a cut in benefit levels combined with a decrease in transfer withdrawal is shown to produce somewhat larger employment effects of about 190?000 individuals. 相似文献

Oil shocks are generally acknowledged to have important effects on both economic activity and macroeconomic policy. The aim of this paper is to investigate how oil price shocks affect the growth rate of output of a subset of developed countries by comparing alternative regime switching models. Different Markov–Switching (MS) regime autoregressive models are, therefore, specified and estimated. In a successive step, univariate MS models are extended in order to verify if the inclusion of asymmetric oil shocks as an exogenous variable improves the ability of each specification to identify the different phases of the business cycle for each country under scrutiny. Following the wide literature on this topic, seven different definitions of oil shocks which are able to describe oil price changes, asymmetric transformations of oil price changes, oil price volatility, and oil supply conditions are considered. 相似文献

Network Rail's decision in 2003 to bring track maintenance back in-house was long-overdue recognition that responsibility for safety on Britain's railways cannot be abdicated – but there was more to it than that. The accidents at Hatfield and Potter's Bar (both in Hertfordshire, UK), in particular, had exposed very vividly how privatisation had encouraged each now separated and competing part of the industry to operate in its own interests: records, data and expertise were fragmented, and track and train operators alike each sought to minimise their individual costs in isolation. This paper argues from a systems analysis perspective that, on vehicle and track maintenance at least, the overall costs to the industry are in such circumstances likely to be higher than if the various parties were to work together towards minimising total track and train maintenance costs between them. Far from increasing efficiency, privatisation had the effect of reducing it. 相似文献

We study the effect of the tie strength of inter-firm R&;D partnerships on the innovation performance of companies in four high-tech sectors (pharmaceuticals, computers, semi-conductors and telecom). Returning to Granovetter's (1973) seminal contribution, tie strength is analysed through a broad multi-dimensional perspective. We find that inter-firm R&;D network ties that are stronger in terms of their extent (measured by the length and multitude of R&;D partnerships) and weaker in terms of their depth (the degree of cooperation and the similarity of ties of companies) improve the innovation performance of companies. Interestingly, we find strong support for the role of these R&;D ties in the context of the run-of-the-mill innovation performance of companies. However, there is no support for this effect on significant innovations of companies. 相似文献

Shadow economy and unemployment rate in USA: is there a structural relationship? An empirical analysis 总被引:1,自引:0,他引:1
This article aims to estimate the size of the US shadow economy (SE) using a structural equation approach and to evaluate if a structural relationship exists between the SE and the unemployment rate (UR) in the United States. The size of the SE is estimated to be decreasing over the last two decades. We corroborate the existence of a structural relationship between the SE and the UR by using a simple theoretical model. Furthermore, we extend the Okun's law to estimate the structural relationship between growth rate of official GDP, SE and UR. Our results indicate a significant positive relationship between the SE and the UR. 相似文献

Many studies developed their framework for sustainability through indicator systems, but the interactions and relationships within these indicators have not been studied yet. In this article, based on indicator systems, we use a sample of 78 mining cities in China and employ structural equation modelling (SEM) method to explore the validity of sustainability framework. Our empirical results show that resources abundance positively affects urbanization level significantly but negatively affects cleaner production level and environmental protection level significantly; economic strength positively affects urbanization level significantly; cleaner production level has a significant effect on economic strength and non-mineral resources conversion efficiency. We also find that when economic strength is low, resources abundance might weaken the positive effect of economy on urbanization. 相似文献

Recent studies have indicated that the terms ‘NAIRU’ (non-accelerating inflation rate of unemployment) and ‘natural rate of unemployment’ are not interchangeable. While NAIRU is an empirical macroeconomic relationship estimated via a Phillips curve, the natural rate is an equilibrium condition in the labour market, reflecting the market's microeconomic features. This study evaluates comparatively the inflation-forecasting power of alternative time-varying estimates of the natural rate of unemployment relative to the NAIRU. The natural rate of unemployment in the USA since the Second World War is estimated. Three alternative methods are utilized: the Kalman filter, a structural determinants approach, and the Hodrick-Prescott filter. The section that follows assesses how each estimator of the natural rate compares with the others – as well as with the NAIRU derived from a Phillips curve – in forecasting inflationary changes in the USA in the second half of the twentieth century. The analysis reveals that the overall inflation-forecasting utility of the natural rate of unemployment relative to the NAIRU is not very different. Moreover, the conclusion appears to be quite robust to various estimators of the natural rate. 相似文献

Using a computable equilibrium model, the short-run effects of a radical liberalization of the West European natural gas and electricity markets are examined. In each model country, oil, gas, coal and electricity are produced, traded and consumed. There are world markets for oil and coal, and well-integrated competitive markets for gas and electricity in Western Europe. Gas and electricity are transported and traded across markets under the assumption of ideal third-party access regimes for transportation and limited capacities in the transportation networks. It is found that relative to the data year 1996, radical liberalization reduces the average end-user price of natural gas by around 20%, and the average end-user price of electricity by around 50%. The supply of electricity increases by around 20%, mainly due to increased coal power production. After such liberalization, coal power emerges with the largest market share of electricity production in Western Europe. 相似文献

This paper investigates whether the Global System of Trade Preferences among developing countries (GSTP) achieves its intent to increase the trade of capital goods between member countries. For this purpose, trade data disaggregated by the degree of commodity differentiation and various GSTP regional dummies are employed in a gravity equation. Estimation results say that the value of trade between GSTP member countries has increased significantly since the formation of the GSTP in 1989, and the trade of differentiated commodities has increased remarkably compared with other commodities. Therefore, it can be asserted that the mission of the GSTP has been accomplished successfully. 相似文献

This article considers the impact of match results on the stock returns of English football clubs. We propose that the magnitude of the response to a given result depends on the importance of the game, which is measured in two ways. First, we consider the extent to which the clubs are close rivals vying for similar league positions, as winning such games is particularly significant. Second, we argue that each individual game becomes more important for those clubs likely to be promoted or relegated as the season draws to a close, since a given match will have increasing information content concerning the final league position of the club. Using a fairly large panel comprising data for 19 clubs, we find some support for the notion that stock prices are affected more by the results of important matches than matches of lesser importance. We also observe that the difference between the number of points the club secures from a given match, and the number it was expected to secure, affects its stock price, as does the number of goals that the club under question scores in the match, relative to its competitor. 相似文献

This article revisits a system of export volume and price equations to estimate the long–run price and income effects in the demand for Hong Kong's exports. Using a recently developed restricted cointegrating VAR approach it tests theorybased restrictions and obtains estimates of the long–run structural coefficients. The estimation results provide supporting evidence for the theory–based restrictions and suggest that the demand for Hong Kong's exports is both price and income elastic. This article is therefore able to present a long–run model of Hong Kong's exports that is both theory and data consistent, and long–run elasticities that are economically interpretable. The short–run properties of the model are illustrated by means of persistence profiles, which confirm the cointegrating vectors tendency of convergence. 相似文献

The aim of this paper is to investigate the ways in which social entrepreneurship knowledge is both propelled and hindered by the socioeconomic circumstances. We examine the existing body of research and identify different conceptualizations and main schools of thought. We then demonstrate how the process of constructing academic representation is shaped by the prevalent public discourses. Our analysis leads to the differentiation between social entrepreneurship as mitigation and social entrepreneurship as transformation. We conclude that a better alignment of the two approaches – broadening research focus from outcome to process – would reveal their complementarity and contribute to the conceptual advancement of the discipline. We propose expanding the existing approaches with the politics of social entrepreneurship studies and stress the importance of increased reflexivity on the plight of the new discipline. 相似文献

This paper examines the implications of lag structure for estimating the effects of monetary policy shocks in a VAR. A symmetric lag structure in which all variables have the same lag length and an asymmetric lag structure in which the lag length differs across variables but is the same for a particular variable in each equation of the model are examined. This is important in light of the fact that the true lag structure is generally not known. Four commonly used identification schemes are employed to identify monetary policy shocks. Monte Carlo simulations strongly indicate that the lag structure of a VAR model does matter when assessing the quantitative effects of monetary policy shocks. Given the inherent uncertainty about the true lag structure in practice, it is thus important that one compare the impulse response functions from both symmetric lag and asymmetric lag VARs in assessing the effects of monetary policy shocks. 相似文献
