Housing supply elasticity in local government areas of Sydney

We report supply elasticity estimates of residential property (houses and apartments) for local government areas (LGAs) in metropolitan Sydney. Using annual data for 1991–2012, the average supply elasticity estimate across all LGAs is 0.2 for houses and 0.8 for apartments. The supply of houses is inelastic in all 43 LGAs; in contrast, apartment supply is elastic – greater than unity – in about one-third of LGAs. We develop theoretical and empirical models to explain the cross-section variation in supply elasticity across LGAs. For houses, supply elasticity is negatively related to an LGA’s population density, the time taken by a local council to process a development application and to different measures of the amount of land in an LGA that is unavailable for new housing development. In contrast to houses, variation in supply elasticity for apartments across LGAs is unrelated to any of the available regressors.     

Nonlinearity in dynamic adjustment: Semiparametric estimation of panel labor supply

We estimate a semiparametric dynamic panel data model by the local linear kernel method and we interpret the slope of the nonparametric component function as a varying slope coefficient. Thus, the slope coefficient is a smooth, but otherwise unknown, function of some of the regressors. A Monte Carlo experiment is reported to examine the finite sample performance of the local linear estimator. We apply the estimation method to a labor supply equation for men from the triannual Survey of Income and Program Participation (SIPP). Specification tests based on the estimated labor supply elasticities, partial adjustment coefficients, and residuals demonstrate the improvements from a semiparametric partially linear model. Our empirical results point to a need by economists to revisit the issue of the speed of labor market adjustment to policy induced shifts in labor demand and to take more formal econometric account of heterogeneity in wage effects when studying the distributional consequences of tax reforms for labor supply earnings.

Rural credit and the time allocation of agricultural households: The case of PRONAF in Brazil

This paper evaluates the impact of Brazil's National Program to Strengthen Family Farming (PRONAF) on the time allocation of household members. We use data from the 2014 Pesquisa Nacional por Amostra de Domicílios, and we apply propensity score methods to complex surveys recently recommended in the literature. We find that PRONAF helps to increase focus on agricultural activities, but it also stimulates female partners to engage in unpaid work. The results show significant effects of PRONAF on child labor and on the gender‐specific division of labor within households, although it does not have the usual adverse effects of rural credit programs on school attendance.     

Nature of transfers,income tax function and empirical estimation of elasticity of taxable income for Brazil

This article aims to estimate the elasticity of taxable income (ETI), taking into account the nature of transfers and their use as a redistribution package (involving cash and in-kind transfers) to households in Brazil. Our contributions are twofold. First, we provide a simple model with balanced-budget government that reveals the role played by cash and in-kind transfers on the labour supply (and income tax revenues thereof). Next, in order to estimate ETI in the presence of cash and in-kind transfers, Brazilian population surveys (Pesquisa Nacional por Amostra de Domicílios [PNAD]) are used to explore a limited tax reform that was implemented between 1997 and 1998. This reform only affected the higher income tax bracket. Our findings suggest that in-kind (cash) transfers are positively (negatively) associated with reported taxable income and precise estimation of ETI requires estimates of both types of transfers. Last, we estimate the ETI for Brazil in the range from 0.4 to 1.3 not different from those that maximize income tax revenues.     

The predictive value of subjective labour supply data: A partial-adjustment model with measurement error

This paper tests the predictive value of subjective labour supply data for adjustments in working hours over time. The idea is that if subjective labour supply data help to predict working hours, the subjective data must contain at least some information on individual labour supply preferences. In this paper, I formulate a partial-adjustment model that allows for measurement error in the observed variables. Applying estimation methods that are developed for dynamic panel data models, I find evidence for a predictive power of subjective labour supply data concerning desired working hours in the German Socio-Economic Panel 1988–1995.I wish to thank John Haisken-DeNew, Astrid Kunze, Markus Pannenberg, Winfried Pohlmeier, Frank Windmeijer, Rainer Winkelmann, my former colleagues at IZA and two anonymous referees for their valuable comments.

The motor vehicle industry in an emerging nation: the case of Brazil

As in other emerging nations, in Brazil, the motor vehicle industry is considered to be strategically important for economic development because of its backward and forward linkages and possibilities for export-led growth. This study analyses prospects for the industry by estimating an industry-level cost function that includes output of both vehicles and component parts with capital, labour and intermediate goods as inputs. The cost elasticity of output (an indicator of scale properties) and the elasticity relationships among inputs are explored. One unexpected outcome of the work that appears to be robust is that during early years of the study period, the industry had constant returns or even diseconomies of scale. However, during later years, when output was greater, there were economies of scale. This finding is likely the result of some combination of the entry of new firms, the development of new models or technological change. The study concludes that if firm output can be increased, economies of scale can be expected to strengthen the position of the Brazilian industry in the international marketplace.     

货币需求弹性、有效货币供给与货币市场非均衡模型——解析"中国之谜"与长期流动性过剩

Chinese excessive liquidity problems are more serious than other main countries. The upgrading industrial structure and the increasing opening degree lead to the excessive money demand and higher money demand elasticity. Bad credits weaken money supply effectiveness and lead to illusive increasing money. We set up the money market disequilibrium model under the condition of the excessive liquidity. The imbalance between money demand and money supply is the key of Chinese excessive liquidity problems. __________ Translated from Jingji lilun yu jingji guanli 经济理论与经济管理(Economic Theory and Business Management), 2007, (11): 38–44     

On the relative importance of demand and supply shocks: a panel VAR study for US states

This article is a panel VAR study of demand and supply shocks in the USA using state-level data where structural shocks are decomposed into state idiosyncratic and common components. Decomposition suggests that in all instances, idiosyncratic state shocks rather than common shocks have larger impact and explain most variation in both the state-level unemployment rate and real gross state product. Further, demand shocks are the primary driving force in unemployment rate fluctuations, while both demand and supply are important in output movements to varying degree of impact and importance depending on the use of quarterly or annual data.     

Comparing employment estimates using different minimum wage variables: the case of Brazil

Several minimum wage variables have been suggested in the literature to estimate the effect of the minimum wage on employment. The most common ones are the real minimum wage, the ‘Kaitz index’, the ‘fraction affected’, the ‘fraction at’ and the ‘fraction below’. This diversity of variables makes it difficult to compare the associated estimates across studies. One problem is that these estimates are not always calibrated to represent the employment effect of a 1% minimum wage increase. Another problem is that these estimates measure employment effects for different groups of workers. In this paper we critically compare employment effect estimates using these five minimum wage variables and data from a Brazilian monthly household survey panel from 1982 to 2000. Our principal finding is that the sign of this effect is robust across the different minimum wage variables, but that its magnitude and significance are sensitive to the minimum wage variable used.     

Determinants of obesity in Brazil: the effects of trade liberalization and socio-economic variables

This article aims to evaluate a possible relation between increased Brazilian trade openness and increasing observed rates of overweight and obesity during the last 25 years. We develop an economic model where formal trade barriers are eliminated, and resulting sociocultural outcomes such as the adoption of westernized lifestyle in traditional non-western countries prevails, which could imply a health externality. In order to empirically analyse the influence of trade flows on overweight and obesity in Brazil, a balanced fixed-effects panel model has been estimated. Data for the 26 Brazilian states plus the Federal District are run for 1988/1989, 2002 and 2008. We found that an increase in trade openness leads to an increase in overweight and obesity ratios in Brazil. Hence results seem to point that there is a health externality in Brazil due to trade liberalization. However, more consistent evidence may be necessary to convince politicians and policymakers that any interference will be necessary to correct this externality.

Conflicts of supply chains in multi-channel marketing: a case from northern Finland

Multi-channel marketing is a popular research theme of marketing management. Studying multi-channel marketing is a popular research theme of marketing management. The studies emphasise the necessity and advantages of multi-channel marketing. Despite these advantages, multi-channel marketing is also a source of conflicts in supply chains because the coordination of supply chain ecosystem is challenging. This study is based on a questionnaire and interviews of entrepreneurs. The large significance of dealer, large turnover and the intention to bypass middlemen in the supply chain are sources of conflicts. Variables, which seem to have decreasing effects on conflicts are ‘large number of employees’, ‘intentions to sell different products via different channels’ and slightly in the case ‘to achieve competitive advantage via online shop’. Successful exploitation of e-commerce and multi-channel marketing needs intensive adaptation of entrepreneurs in each step. Each marketing channels need their own planning and sub-strategies. The strategic decisions of e-commerce are part of the whole strategy of the entrepreneurs and the firm.     

Productivity versus elasticity: a normalized constant elasticity of substitution production function applied to historical Soviet data

This study tests the extensive growth hypothesis, which would attribute the Soviet economic slowdown to low elasticity of substitution and over-investment rather than deteriorating productivity growth. To circumvent the low availability of data, widely applicable new methods for estimating productivity and elasticity of substitution were developed based on the normalized constant elasticity of substitution (CES) production function. One is an extended version of the Solow residual calculation, and the other is a direct estimation of the time-varying parameter normalized CES production function. The application of the methods to the Soviet data showed a decreasing trend in productivity growth and a low elasticity of substitution of approximately 0.25. The results neither reject nor support the extensive growth hypothesis because of uncertainty in the interpretation of the low elasticity of substitution. The results suggest that it is reasonable to assert that both deteriorating productivity growth and low elasticity of substitution caused the Soviet economic slowdown. Further empirical studies on productivity and elasticity of substitution in the Soviet and other economies are necessary to fully understand relations between productivity growth, elasticity of substitution and economic development.     

Curvature and the elasticity of substitution: Straightening it out

This paper demonstrates that, contrary to deeply rooted beliefs, there is no link between curvature and the elasticity of substitution. We show that there is no direct, nor inverse, relationship between the two concepts, if curvature of the isoquant is defined either in its strict mathematical sense or as the isoquant's second derivative. We finally suggest to view the elasticity of substitution as an efficiency parameter.

A synthetic cohort analysis of female labour supply: the case of Thailand

This study analyzes trends and patterns in employment, hours worked, and women’s wages for Thai women, and relations among these variables in models of female labour supply. Labour supply behaviour of Thai women is investigated with synthetic cohort data defined by age, year of birth, and level of educational attainment, constructed from annual labour force surveys from 1985 to 2004. According to pseudo-panel estimates, wage increases lead to a reduction in hours worked, but also an increase in the employment/population ratio, with elasticity estimates that are robust across a variety of specifications. Estimates based on disaggregation by marital status show that marriage provides protection against wage decreases, allowing married women greater choice between hours of work and other household activities. Alternative disaggregations find that younger cohorts of women and those with the highest education show the greatest (positive) response of the employment rate to wage changes, leading to a future Thai labour force with more women and higher educational attainment.     

Evaluating innovation and labour market relationships: the case of Italy

In this paper the link between labour market flexibility andinnovation is analysed paying particular attention to the differenttechnological regimes of economic activities and the differentgeographical areas of the Italian economy. A dynamic panel dataspecification is used to assess the endogenous relationshipbetween patents, included as a proxy for innovation, and jobturnover and wages, which represent labour market indicators.Our results show that higher job turnover only has a significantand negative impact on patent activities in regional sectorsof Northern Italy, while blue and white collar wages have beengenerally found to have a positive and significant impact oninnovation.
