Firms' relative sensitivity to aggregate shocks and the dynamics of gross job flows

We propose the coefficient of variation as a measure of the cyclical volatility of gross job flows that is immune to trends in net job creation. In addition, we show that this measure is intrinsically related to the importance of aggregate shocks for fluctuations in job flows at the firm level. Using data for the Portuguese economy, we conclude that the coefficient of variation is a more robust measure for the underlying volatility of gross job flows. We also find that large and old firms exhibit higher relative sensitivity to aggregate shocks than small and young firms, and have a disproportional influence over the dynamics of aggregate job reallocation. In particular, since large and old firms tend to reallocate jobs less procyclically than small and young firms, job reallocation is less procyclical than if all firm classes were equally sensitive to aggregate shocks.     

EFFECTS OF LABOR REALLOCATION ON PRODUCTIVITY AND INEQUALITY—INSIGHTS FROM STUDIES ON TRANSITION

From a theoretical perspective, the link between the speed and scope of rapid labor reallocation and productivity growth or income inequality is ambiguous. Do reallocations with more flows tend to produce higher productivity growth? Does such a link appear at the expense of higher income inequality? We explore the rich evidence from earlier studies on worker flows in the period of massive and rapid labor reallocation, that is, the economic transition from a centrally planned to a market-oriented economy in CEE. We have collected over 450 estimates of job flows from the literature and used these inputs to estimate the short-run and long-run relationship between labor market flows, labor productivity, and income inequality. We apply the tools typical for a meta-analysis to verify the empirical regularities between labor flows and productivity growth as well as income inequality. Our findings suggest only weak and short-term links with productivity, driven predominantly by business cycles. However, data reveal a strong pattern for income inequality in the short run—more churning during reallocation is associated with a level effect toward increased Gini indices.     

A structural model of US aggregate job flows

This paper contributes to the analysis of jobs flows dynamics through the explicit modelling of job creations and job destructions. We propose a simple matching model extended for endogenous separation and tractable heterogeneity. The parameters of the model are estimated using a simulation‐based estimation method. We then test the ability of trade externalities, generated by the matching process, to (i) propagate reallocation and aggregate disturbances in the whole labor market and (ii) generate the observed distribution of aggregate job flows. The results clearly indicate that the model is able to match the dynamics of US aggregate job flows. Copyright © 2002 John Wiley & Sons, Ltd.     

Oil Prices and Personal Consumption Expenditures: Does the Source of the Shock Matter?

This paper studies the effect of structural oil shocks on personal consumption expenditures (PCE). First, we estimate a nonlinear simultaneous equation model, compute impulse responses by Monte Carlo integration, and conduct a test of the symmetry of the impulse response functions. We find that aggregate PCE responds asymmetrically to positive and negative oil‐specific demand shocks. Second, we find that aggregate PCE responds negatively to positive oil demand shocks, while adverse oil supply shocks are of limited effect. Third, we find important heterogeneity in the magnitude, sign and timing of the disaggregate PCE responses to structural shocks in the crude oil market. Our results clearly indicate that the response of PCE to an unexpected oil price increase depends on the source of the oil price shock. Our findings are robust to different nonlinear transformations for the real price of oil.     

The Hiring Function Reconsidered: on Closing the Circle

This paper investigates the matching of job searchers with vacant jobs: a key component of the dynamics of worker reallocation in the labour market. The job searchers may be unemployed, employed or not in the labour force and we estimate matching or hiring functions including all three groups. We show that previous studies, which ignore both employed job seekers and unemployed job seekers who are considered to be out of the labour force, produce biased estimates of the coefficients of interest. By considering only unemployment outflows into jobs and ignoring interdependencies with other flows, these studies overlook an important aspect of job matching. Our estimates on Australian data support a more general approach and produce models that dominate those proposed previously. We find that concentrating on the aggregate matching function alone does not reveal the full extent of the interaction across job searchers. Indeed, we find that job searchers from the three groups do not receive a fair share of hires: there appears to be segmentation of hiring opportunities which may be explained by a form of ranking of applicants. Together these results demonstrate that the disaggregate worker flows and their interdependence are key features on the labour market and should be included in studies of the hiring process.     

The nonlinear effect of oil price shocks on financial stress: Evidence from China

This paper examines the nonlinear effects of different types of oil price shocks on China’s financial stress index (FSI). For this purpose, we use newly proposed framework by Ready (2018) to decompose oil prices into supply, demand and risk shocks. Then, we use a Markov regime-switching (MRS) model to investigate the nonlinear effects of these oil price shocks on China’s FSI. The empirical results show that the effects of three oil price shocks are nonlinear under different regimes. In particular, oil supply shocks mainly have a significantly positive effect on China’s FSI in the low-volatility state; demand shocks have negative effects on China’s FSI in different regimes, but this effect is larger in the low-volatility state; the effect of risk shocks on China’s FSI is the opposite, and it is positive in the high-volatility state but negative in the low-volatility state.     

Job flows,jobless recoveries,and the Great Moderation

This paper explores a link between the decline in employment volatility and the onset of jobless recoveries observed since the mid-1980s using a time series of job flow estimates for manufacturing that covers the entire postwar period. I show that job creation and job destruction rates have fallen and become less cyclical. This has increased the importance of reallocative shocks relative to aggregate shocks in explaining their time-series fluctuations. Despite the increased importance of reallocation, it is a change in the responses of job flows to aggregate shocks, which are now larger and more persistent, that lead to the onset of jobless recoveries. The decline in the cyclicality of temporary layoffs and the rise in the use of employment services cannot account for these altered responses.     

The cyclical pattern of regional unemployment flows in Poland

Using male unemployment benefit data across Polish regions during 1994–1996, we find that unemployment flows are pro-cyclical and increase with job reallocation, controlling for other factors. At the national level we observe that job reallocation and output are associated with stagnant unemployment flows, low inflows and long duration. This has heretofore been attributed to workers by-passing the unemployment benefit system as they move job to job. We show this to be a fallacy of aggregation. The cyclical behaviour of regional unemployment flows and their response to job reallocation suggests that workers use unemployment benefit system to facilitate transition.     

Macroeconomic responses of emerging market economies to oil price shocks: An analysis by region and resource profile

We analyze the impact of oil price shocks on the macroeconomic fundamentals in emerging economies in three regions that have different resource endowments. The existing literature on emerging economies remains inconclusive on how regional factors and resource characteristics affect the response of macroeconomic variables to oil price shocks. We show that (1) exports in Europe and Central Asia are driven by oil more than East Asia and the Pacific and that (2) policy makers in East Asia and the Pacific should be concerned about real exchange appreciation following a positive oil shock to mitigate losses in the non-oil export market. Analysis by resource endowment further reveals that, in less-resource-intensive economies, an oil price shock causes large variations in consumption and has a negative and persistent impact on the real gross domestic product (GDP). In mineral-exporting economies, real GDP and interest rates are driven largely by oil price shocks. The response of real GDP in mineral-exporting economies is short lived. In oil-exporting economies, only real GDP has a large variation in response to oil price shocks. Our findings highlight the need for customized policy responses to oil price shocks, depending on resource endowments, as we show that a “one size fits all" policy does not exist.     

The importance of education for the reallocation of labor: Evidence from Swedish linked employer–employee data 1986–2002

Using Swedish employer–employee data we study job and worker flows for different educational groups, as well as the cyclicality of such flows. Due to the long period studied, from 1986 to 2002, and the widely fluctuating business cycle during this period, we have a unique opportunity to analyze the cyclical pattern of job and worker flows. We especially look at the big downturn in the Swedish economy in the beginning of the 1990s. When workers are treated as homogenous, we find job reallocation to be countercyclical. However, when we estimate correlations for different educational groups, we find job reallocation to be countercyclical for the lowest educated, and acyclical for higher educated workers. Contrary to job flows, we find worker flows to be acyclical, with a strong procyclical pattern in hiring rates, and an acyclical pattern in separation rates. When decomposing worker flows into educational groups, the acyclical pattern is prevalent for all groups, except for the highest educated. For the highest educated, worker reallocation is strongly pro-cyclical due to both more hirings and separations during up-turns.     

Local labor market impacts of energy boom-bust-boom in Western Canada

The impacts of energy price boom and bust are analyzed through the differential growth in employment and earnings between local labor markets with and without energy resources in Western Canada. The estimated differentials attributed to the boom-induced labor demand shocks show significant direct and indirect impacts on the earnings and employment within the energy extraction and other non-energy local sectors respectively. The local job multipliers indicate that job creation within the energy extraction sector leads to modest job creation within the non-energy local sectors during boom periods. For every ten energy extraction jobs created during a boom period, approximately three construction jobs, two retail jobs, and four and a half service jobs are created.     

Oil price shocks and unemployment in Central and Eastern Europe

The aim of this paper is to examine the effect of oil price movements on unemployment in Central and Eastern Europe. We do this by disentangling oil prices movements by their sign and from there we analyse the separate effects of positive and negative movements of oil prices on unemployment rates. We find that, although oil prices and unemployment are not correlated very much in the short run, the effect of oil price shocks on the natural rate of unemployment goes in the same direction, so that increases or decreases in oil prices increase or decrease the natural rate of unemployment.     

Structural analysis and forecast of gold price returns

Gold has multiple attributes and its price is affected by various factors in the market. This paper studies the dynamic relationship between the gold price returns and its affecting factors. Then we use the STL-ETS, neural network and Bayesian structural time series model to predict the gold price returns, and compare their performance with the benchmark models. The results show that the shocks of crude oil returns and VIX have the positive effect on gold price returns, the shocks of the US dollar index have the negative effect on gold price returns. And the fluctuation of gold price returns mainly depends on crude oil price returns shocks. STL-ETS model can accurately fit the fluctuation trend of the gold price returns and improve prediction accuracy.     

Economic uncertainty,oil prices,hedging and U.S. stock returns of the airline industry

This paper examines the impacts of economic policy uncertainty and oil price shocks on stock returns of U.S. airlines using both industry and firm-level data. Our empirical approach considers a structural vector-autoregressive model with variables recognized to be important for airline returns including jet fuel price volatility. Empirical results confirm that oil price increase, economic uncertainty and jet fuel price volatility have significantly adverse effect on real stock returns of airlines both at industry and at firm level. In addition, we also find that hedging future fuel purchase has statistically positive impact on the smaller airlines. Our results suggest policy implications for practitioners, managers of airline industry and commodity investors.     

The search for success: do the unemployed find stable employment?

We use discrete time proportional hazards regressions to model the impact of previous unemployment incidence and duration on job tenure. We find that jobs that follow an unemployment spell have shorter mean duration than other jobs. Only one half of jobs that follow unemployment last for 12 months. Multivariate results suggest that an unemployment spell has a severe penalty on subsequent job tenure, and that it is unemployment incidence rather than duration which has the major impact.     

Oil prices,economic activity and inflation: evidence for some Asian countries

In this paper we study the oil prices–macroeconomy relationship by means of studying the impact of oil price shocks on both economic activity and consumer price indexes for six Asian countries over the period 1975Q1–2002Q2. The results suggest that oil prices have a significant effect on both economic activity and price indexes, although the impact is limited to the short run and more significant when oil price shocks are defined in local currencies. Moreover, we find evidence of asymmetries in the oil prices–macroeconomy relationship for some of the Asian countries.     

Job evaluation systems and pay grade structures: do they match?

Job evaluation is usually applied in an organization in order to assess the relative value of jobs on the basis of which jobs are assigned to classes of pay grades. Thus, the assumption is that job value scores match with pay grade structures, and allow adequate predictions of basic job wages or salaries in practice. The validity of this assumption is questioned in this article. Data of five job evaluation systems (number of jobs: 16,809) were used to assess the effects of three system manipulations, concerning the number of anchors per scale (characteristic), the nature and the number of scales, and the weights of scales. Total job value scores of the manipulated data and the associated pay grades were compared with the non-manipulated ('original') scores. It turned out that even when two sets of job value scores are highly correlated (around 0.99), pay grade classification agreement was always less than 90 per cent, and in many instances much less. This result has important implications for the use of job evaluation in practice: when a fine grained system of pay grades applies, total job value scores may be deficient. Implications for a better match between total job worth values and pay grade classes are discussed.     

The effects of oil price shocks on inflation in the G7 countries

This study examines the effects of three types of oil price shocks on inflation in the G7 countries with a new method of isolating oil price shocks. Based on monthly data from January 1997 to January 2019, we find that each oil price shock has the largest effect on U.S. inflation among the G7 countries and each country’s response to oil price shocks is different. Moreover, a rolling-window analysis shows that supply shocks, demand shocks and risk shocks have dynamic effects on inflation. The effect of supply shocks on inflation is strong before the financial crisis, but weakens during the crisis. However, the effect of demand shocks increases sharply in this time. The effect of risk shocks mainly occurs during the financial crisis and the European debt crisis. In addition, this study uses two ways to verify the robustness of the results. Our empirical results have important implications for policymakers and manufacturers, since the results provide a good explanation for the response of inflation in the G7 countries to the oil price shocks from different sources.     

The impact of oil price changes on selected macroeconomic indicators in Azerbaijan

We examine the relationship between oil price fluctuations and economic activity in Azerbaijan using vector autoregressive models for the period 2002Q1–2018Q4. Our key results are as follows. First, growth in the gross domestic product (GDP) decreases after oil price innovations in the oil and gas sector and in the remainder of the economy. Downturns (upswings) in the oil and gas sector also prompt downturns (upswings) in the non-oil sector as fluctuations in oil revenues affect the government's capacity to subsidize the rest of the economy. Second, oil price innovations also lead to higher inflation in Azerbaijan. In response to the required tightening of monetary policy, the manat appreciates against the US dollar. Finally, GDP effects are primarily seen after oil price increases, whereas the interest rate and the exchange rate mainly react to decreases. Inflation increases after both types of shocks, due to either the accommodative monetary policy stance in the case of oil price decreases or the shock itself in the case of increases.     

The Reallocation of Labour and the Lifecycle of Firms

This paper uses a unique US panel dataset of firms and workers toinvestigate the relationship between the firm's lifecycle and the reallocation of labour. We distinguish labour reallocation associated with job reallocation, and reallocation of workers over a fixed configuration of jobs. We find that firms at the beginning and end of their lifecycles contribute disproportionately to labour market lows, with sorting between firms particularly important among young firms, whereas sorting within firms is moreimportant among mature firms. We also find that high churning lows are associated with a lower probability of a young firm surviving.
