Has Switzerland Really Been Marked by Low Productivity Growth? Hours Worked and Labor Productivity in Switzerland in a Long‐run Perspective

This paper shows that previous work has understated Switzerland's performance in terms of labor productivity growth. First, available data on hours worked are incoherent and overestimate growth in hours worked. The paper therefore establishes a consistent series of total hours worked and its components covering 1950–2010, showing that Swiss labor inputs actually were stable from 1964 to 2007. Second, long‐term improvements in Switzerland's Terms of Trade indicate that quality improvements in Swiss exports might not be fully mirrored in growth of GDP and, hence, productivity growth.     

Is the Phillips Curve A Curve? Some Evidence and Implications for Australia

The Phillips curve has generally been estimated in a linear framework. This paper investigates the possibility that the Phillips curve is indeed a curve, and shows that a convex short-run Phillips curve may be a more accurate representation of reality than the traditionally used linear specification. The paper also discusses the policy implications of convexity in the Phillips curve. These include the need for policy to be forward looking and to act pre-emptively. Convexity provides a strong rationale for stabilization policy, and it reinforces the need for policy makers to proceed cautiously. It also implies that deep recessions may have only a marginally greater disinflationary impact than shallower ones, unless they induce large credibility bonuses.     

Is the Phillips Curve Valid in China?

Is the “non-existence” of the Phillips curve in China a truth or just an illusion due to the deficiency of data? Should policy analysis follow the light of New-Keynesian or New-classical economics? These questions require empirical work on the Phillips curve, which has long been limited in China due to an inaccurate unemployment rate and unreliable estimated output gap. Instead of the insignificant or self-contradicting results in previous work, this paper puts forward a significant estimation, creatively using the vacancy-jobseeker ratio instead of the unemployment rate. It is suggested that a robust Phillips curve cannot be ignored and New-Keynesian economics should be employed in policy analysis in the short run.     

Why Do Some Households Save So Little? A Rational Explanation

This paper offers an explanation for the puzzle of low wealth holdings among a significant fraction of the elderly. Instead of invoking irrational, nonrational, or nonoptimal behavior to resolve the puzzle, it is shown that widespread low wealth holdings are consistent with a rational life-cycle model of saving with uncertain lifetime and borrowing constraint. When there is uncertainty about the length of life, it is optimal for some individuals to save little and exhaust their wealth early. The characteristics of these individuals are derived. The simulation results support that the model can account for low wealth holdings as well as early terminal wealth depletion. The analysis also rejects the common perception that uncertain lifetime reduces dissaving. Journal of Economic Literature Classification Numbers: D11, D91, E21, I12, J14.

Why Has the Workplace Become Safer?

This paper asks whether the fall over 1983–1993 in the aggregate injury-to-workforce ratio (the injury rate) that occurred in Queensland was due to improvements in industrial safety or due to shifts in employment away from 'unsafe' industries. The conclusion, based on data from the Queensland Employee Injury Data Base, is that improvements in industrial safety were the main reason for the State's workplace becoming safer. The paper then conducts an econometric investigation in to why industrial injury rates in Queensland fell over 1983–1993. The evidence is that in Mining, Manufacturing and Construction, there was a significant autonomous decrease in the injury rate. The problem is that since the data available were only for those injuries against which compensation was claimed, it is difficult to say—except as a matter of judgement—whether improvements in injury rates in these sectors were due to genuine improvements in safety or caused by a fall in the propensity to claim compensation. Changes in general economic conditions—particularly, rising unemployment—have also contributed to falling injury rates.     

Why Do the Rich Save More? A Theory and Australian Evidence*

We provide a theory to explain the existence of inequality in an economy where agents have identical preferences and have access to the same production technology. Agents consume a ‘health’ good which determines their subjective discount factor. Depending on initial distribution of capital the economy gets separated into different permanent‐income groups. This leads to a testable hypothesis: ‘The rich save a larger proportion of their permanent‐income’. We test this implication for savings behaviour in Australia. We find that even after controlling for lifecycle and health characteristics, higher permanent income is positively related with higher savings rates and better saving habits.     

Is the Hybrid New Keynesian Phillips Curve Stable? Evidence from Some Emerging Economies

This paper primarily examines whether the ‘hybrid new Keynesian Phillips curve’ (HNKPC) holds for four important emerging economics viz., Brazil, Russia, India and South Africa. This has been done after testing for the structural stability of this relationship. Econometric issues like the test of unit roots in presence of a structural break and estimation of output gap have also been done appropriately. Our findings suggest that the HNKPC is not stable for all the four countries. However, the analysis based on the two sub-periods thus formed clearly shows mixed evidence in respect of holding of this relationship.

     

Why Has the Fraction of Nonstandard Workers Increased? A Case Study of Japan

This paper explains the secular increase of nonstandard workers in Japan, whose share of employment increased from 17 to 34% between 1986 and 2008. Changes in labor force and industrial compositions account for one quarter of the increase of nonstandard workers. Product‐demand fluctuation and the introduction of information and communication technologies increased firms' usage of nonstandard workers, but its quantitative effects are limited. The increase of nonstandard workers was concentrated among new entrants to the labor market, male workers of younger cohorts, and female workers of all cohorts, suggesting that the declining importance of the long‐term employment relationship is a major cause for the increase of nonstandard workers.     

Why Has Japan Failed to Escape from Deflation?

Japan has failed to escape from deflation despite an extraordinary monetary policy easing over the past 4 years. Monetary easing undoubtedly stimulated aggregate demand, leading to an improvement in the output gap. However, since the Phillips curve was almost flat, prices have hardly reacted at all. Against this background, the key question is why prices were so sticky. To examine this, we use sectoral price data for Japan and seven other countries including the USA, and use these data to compare the shape of the price change distribution across the eight countries. Our main finding is that Japan differs significantly from the other countries in that the mode of the distribution is very close to zero for Japan, while it is near 2% for other countries. This suggests that while in the USA and other countries the “default” is for firms to raise prices by about 2% each year, in Japan the default is that, as a result of prolonged deflation, firms keep their prices unchanged.     

How and Why Has Teacher Quality Changed in Australia?

International research suggests that differences in teacher performance can explain a large portion of student achievement. Yet little is known about how the quality of the Australian teaching profession has changed over time. Using consistent data on the academic aptitude of new teachers, we compare those who have entered the teaching profession in Australia over the past two decades. We find that the aptitude of new teachers has fallen considerably. Between 1983 and 2003, the average percentile rank of those entering teacher education fell from 74 to 61, while the average rank of new teachers fell from 70 to 62. We find that two factors account for much of the decline: a fall in average teacher pay (relative to other occupations) and a rise in pay differentials in non‐teaching occupations.     

Is There a Trade-Off between COVID-19 Control and Economic Activity? Implications from the Phillips Curve Debate

In this paper, we argue that the roles of public policies concerning COVID-19 can be better understood in light of the past discussions on the Great Inflation of the 1970s and the 1980s. Like the Phillips Curve in macroeconomics, the pandemic presents a trade-off between economic activities and something undesirable, which is, in this case, infection. Like the Phillips Curve, this apparent output-infection trade-off is an elusive one and it is lost in the long run. Containing infections calls for decisive policy action. This paper shows that we could design a reaction function, which sets the level of economic activity as a function of the state of infection, in such a way that the possibility of an infection explosion would be eliminated. Our empirical analysis suggests that Tokyo, New York, and London since September 2020 do not satisfy this desirable property.     

Do professional forecasters behave as if they believed in the New Keynesian Phillips Curve for the euro area?

This paper finds that participants in the European Central Bank’s Survey of Professional Forecasters have submitted forecasts that are consistent with a (mostly forward-looking) empirical version of the New Keynesian Phillips Curve for the euro area. The estimation technique takes advantage of the panel nature of the Survey of Professional Forecasters’ dataset to exploit both its time series and cross-section dimensions, and to control for unobservable individual heterogeneity across forecasters. The estimation results suggest that euro-area inflation forecasts have reacted less to unemployment forecasts after the start of the financial crisis but another cost measure (energy inflation) remains significant. This finding is consistent with a flatter Phillips Curve in the euro area after 2007. However, the reasons suggested by the International Monetary Fund for this finding, namely a better anchoring of inflation expectations and increases in structural unemployment do not seem to find support in the survey data. Instead, the expectations for compensation per employee submitted by professional forecasters are consistent with the existence of downward real-wage rigidities in euro-area labour markets.     

The Australian Economy in 2019–20: Slower Growth,Record Low Interest Rates and a Changing Housing Landscape

Economic activity in Australia slowed considerably in 2018–19, with domestic demand growth halving and unemployment rising. Consistent with the slowdown, both consumer and wage inflation have remained weak. A synchronised growth slow-down was observed across major economies, to some extent underpinned by the on-going US–China trade war. Central banks have responded to weak growth by cutting rates. The US Federal Reserve cut its target for the federal funds rate three times in 2019, as did Australia. To date, record low Australian interest rates have been associated with additional housing-related debt and asset price appreciation.     

Does Ecological Footprint Impede Economic Growth? An Empirical Analysis Based on the Environmental Kuznets Curve Hypothesis

This paper examines the relationship between income and environmental quality using environmental Kuznets curve (EKC) hypothesis. The hypothesised link is tested using time‐series analysis of 22 countries over the period 1961–2011. The degree of environmental impacts of economic activity is measured using ecological footprint (EF) per capita as explanatory variable, while real gross domestic product (GDP) per capita and its quadratic and cubic forms are used as predictor variables in these countries. First, the EKC hypothesis is tested through examining the relationship between EF and GDP using linear, quadratic and cubic functions. Further, the long‐run relationship between EF and GDP is investigated using a vector error correction model. It was found that there is a cointegrated relationship between the variables in almost all countries, which was statistically significant, and EKC supported in 10 countries. Additionally, almost all error correction terms are correct in sign and are significant, which implies that some percentage of disequilibria in EF in the previous year adjusts back to the long‐run equilibrium in the current year. Therefore, an efficient trade‐off between environmental protection and economic benefits should be taken, and EF should be reduced through changing consumption patterns, improving the efficiency of use of resources and cleaner technology choices.
