Non‐Standard Time Wage Premiums and Employment Effects: Evidence from an Australian Natural Experiment

We examine the effect of increasing Sunday wage premiums on retail industry employment in Australia, exploiting a quasi‐experimental policy change across two neighbouring states. Using both aggregate and individual‐level data, we adopt a difference‐in‐difference regression framework to estimate the causal impact of the policy change on employment outcomes. We find no evidence of changes in the total number of employees, and no effect on hours per employee in the years following the policy implementation. However, there appeared to be a decline in hours per employee in the announcement year of the policy change. Overall, it appears that in an industry dominated by part‐time and casual employment, any adjustment to the new Sunday wage rates occurred principally through flexibility in hours, rather than in the number of employees.     

Investment behaviour and “bull & bear” dynamics: modelling real and stock market interactions

In this article, we develop a simple behavioural macrodynamic model in continuous-time with the purpose of investigating the interaction of the real economy and the financial markets. Building on Westerhoff (Discret Dyn Nat Soc, 2012), we improve the specification of aggregate demand by distinguishing between consumption and investment expenditure and assuming that the latter is determined by the flexible accelerator principle. We remove the ad hoc nonlinearity in the fundamentalist behavioural rule and allow the composition of the population between chartists and fundamentalists to be endogenously determined. The resulting nonlinear dynamic systems are shown to generate various dynamic regimes, among which the coexistence of periodic attractors with interesting economic implications. Endogenous investment and stock market dynamics emerge, procyclical to each other, reflecting the interaction of induced investment with alternating waves in speculators’ sentiments. We show that a strong investment accelerator might be a crucial force generating fluctuations that, on the one hand, are transmitted and amplified by chartists and, on the other hand, are contained by fundamentalists.

     

Optimal age‐dependent income taxation in a dynamic extensive model: The case for negative participation tax on young people

We consider optimal age‐dependent income taxation in a dynamic model where the labor‐leisure choice is the extensive margin, each household faces idiosyncratic shocks to labor productivity and a pecuniary cost to work, and there is no insurance market against the shocks. We show that the well‐known property of the optimal participation tax rate in the static model continues to hold in our dynamic economy, that is, the participation tax rates for some income groups with low consumption are likely negative. In dynamic models, the optimal participation tax rate depends on age and on labor income. Our numerical simulations suggest that a negative participation tax should be restricted to young households.     

Macroeconomic Volatility,Institutional Instability and the Incentive to Innovate

This study investigates the channels through which macroeconomic and institutional instability hinders innovative investment undertakings financed by the domestic private sector. The analysis is based on a sample of 44 countries and considers various instability dimensions. The results suggest a negative impact of real, monetary and political instability on the aggregate level of R&D financed by the business sector. Thus, highlighting the importance of stable macro‐institutional environments in preventing avoidance or abandonment of private innovation undertakings.     

Expenditure Inequality in Indonesia, 2008–2010: A Spatial Decomposition Analysis and the Role of Education

Based on the 2008–2010 Susenas panel data, this study examines expenditure inequality from spatial perspectives in Indonesia, using three decomposition methods: (i) a conventional Theil index decomposition; (ii) an alternative Theil index decomposition proposed by Elbers et al. (2008); and (iii) the Blinder?Oaxaca decomposition. Our results show that overall inequality in per capita expenditure increases between 2008 and 2010, which coincides with a rising trend in the official Gini coefficient. The contribution of inequality within urban and rural areas to total inequality is larger than that of inequality between urban and rural areas. Looking within urban and rural areas, urban inequality is significantly higher than rural inequality. Java‐Bali in particular records very high urban inequality. Overall, urban inequality increases, urban–rural inequality remains stable, rural inequality decreases, and inequality at the national level increases. Although urban–rural inequality has a relatively low share in overall inequality, the share is not small enough to ignore its impact. Furthermore, when using the alternative decomposition method, the contribution of urban–rural inequality increases substantially. The present study also found that educational differences appear to have played an important role in expenditure inequality within urban areas and between urban and rural areas.     

A Hedonic Analysis of Nutrition and Health Claims on Fruit Beverage Products

This paper investigates the effects on prices of nutrition and health claims for foodstuffs, in addition to other attributes, using fruit beverages as a case study. The model estimation is based on revealed purchasing behaviour for fruit beverages in the north‐east of Italy. Applying an hedonic price model, the price of a product is explained as a function of product attributes. The model estimate identifies the implicit retail‐market‐level price of specific attributes such as nutrition and health claims, ceteris paribus. Nutrition and health claims significantly affect retail prices. Our findings suggest that retail price response to nutrition and health claims differs in relation to other product attributes, showing a strong reduction of price variation among flavours when such benefits are claimed on the label.

Principal components estimation and identification of static factors

It is known that the principal component estimates of the factors and the loadings are rotations of the underlying latent factors and loadings. We study conditions under which the latent factors can be estimated asymptotically without rotation. We derive the limiting distributions for the estimated factors and factor loadings when N$N$ and T$T$ are large and make precise how identification of the factors affects inference based on factor augmented regressions. We also consider factor models with additive individual and time effects. The asymptotic analysis can be modified to analyze identification schemes not considered in this analysis.     

Measuring innovation in services: the role of surveys

The main aim of this paper was to analyse the role of European innovation surveys in measuring innovation in services. The various community innovation surveys (CISs) are analysed in the light of the three main theoretical approaches to innovation in services, namely assimilation, service-oriented and integrative. The analysis performed shows a gradual change in the way in which European surveys have been structured over time, highlighting a partial shift from the assimilation approach towards the integrative one. Furthermore, the paper provides a systematic assessment of the CIS experience and of the lessons to be drawn from it.
