Estimation of a dynamic demand function for gasoline with different schemes of parameter variation

In this article we explore the consumer demand for gasoline within the framework of the household production function model. Working with a time series of regional cross-sections, we find the parameters in the gasoline demand model varying across states. Random coefficient model is utilized to analyze temporal cross-section data.     

Making unilateral trade liberalisation beneficial to the poor

In this paper, we investigate the impacts of unilateral import liberalisation by a representative South Asian developing economy, Nepal, and demonstrate those conditions required to make the impacts ‘pro-poor.’ Applying the Computable General Equilibrium model to Social Accounting Matrix data, we conclude that import liberalisation is growth-enhancing but that, unfortunately, the rich benefit more than do the poor. We envisage a restructured but plausible model economy that requires a transformational period of ten years, and simulate unilateral trade liberalisation but, in the context of a dynamic model. We conclude that improvement in efficiency parameters, reorganisation of investment patterns, along with reallocation of factors of production by both household group and activity type are required to make growth accrued by import liberalisation ‘pro-poor’ in developing economies such as that of Nepal.     

中国多区域社会保障均衡的政策模拟

本文在介绍社会保障研究和多区域CGE进展的基础上,提出将社会保障研究从传统的单区域局部均衡框架推进至多区域一般均衡的研究框架,并构建了一个中国多区域社会保障可计算一般均衡模型(Multi-Regional,MReCGE-C),该模型对居民根据城乡属性和年龄结构进行了分组,放松了要素流动的限制,使劳动力和资本可以同时跨区域流动,并设计了一种基于居民终生效用的区域均衡机制,通过区域变量可以调控和测度区域差距。最后利用MReCGE-C模型针对中国社会保障政策下的两种典型方案进行了模拟。

The Development and Empirical Testing of Extended Input-Output Price Models

The focus in this paper is on the input-output price model as initially developed by Leontief nearly 60 years ago. A number of methodological refinements are proposed, including the formulation, for the first time, of an extended price model, with a disaggregated household sector. This model is presented in both static and dynamic versions. The effects of these refinements are investigated empirically by reference to an example of policy analysis. This relates to a hypothetical proposal to remove energy subsidies at the national level in Iran. The paper reports on the different results produced by each form of price model and also provides evidence on the sensitivity of individual parameter values. The paper concludes by considering the feasibility of constructing more comprehensive versions of the price model and identifying those elements of the model for which data are likely to be more difficult to obtain at national and regional levels.     

A Johansen model for regional analysis

A ‘bottoms-up’ regional model of the Johansen class allowing for price substitution, flexibility in classifying and reclassifying variables into exogenous or endogenous categories, and ease of computation, is constructed to demonstrate the attractiveness of Johansen type models for regional analysis. These models have been used extensively by international trade theorists with success, but surprisingly they have not caught the attention of regional economists.     

Enrolment and Delayed Enrolment of Secondary School Age Children in Indonesia

We analyse the school participation decision of children between 13 and 18 years in Indonesia using the 1992 SUSENAS household survey. Our focus is on which household factors determine enrolment and delayed enrolment. We use the multinomial fixed effect model where the cluster-specific fixed effects correct for any regional-specific factors that may influence the demand for education. The model is estimated by conditional maximum likelihood. We find that parent's education has a positive effect on enrolment, where the effects are stronger for boys than for girls. On the other hand, literacy of parents has stronger effects on the girls education than on the boys'. The model without fixed effects is rejected against the model with fixed effects. Hence, omitting regional variation in the model would have led to biased estimates.     

THE RELATIVE IMPORTANCE OF EXPORTS IN DETERMINING LEVELS OF REGIONAL OUTPUT AND INCOME: A Model and Empirical Evidence from Kenya

Exports have long been assumed by many to be the most important variable in driving regional growth, although factors such as government expenditure, investment demand, and remittances, among others, have also been recognized as significant. In addition, supply-side constraints to the promotion of regional growth and development have recently received increased attention in the literature. This paper evaluates the relative importance of exports, investment demand, and remittances, as well as supply-constrained agricultural production, in determining levels of regional output, value added, and household income in a single region in Kenya. The analysis is based on a mixed endogenous/ exogenous model derived from a social accounting matrix (SAM) which allows for incorporation of both demand and supply-side considerations. The paper finds that exports are, in fact, the most important factor in explaining regional output and wage income in the region studied, although not overwhelmingly so. In addition, the analysis demonstrates the importance of supply-constrained agricultural production as a determinant of income at the household level.     

The role of villages in households’ poverty exit: evidence from a multilevel model for rural Vietnam

Vietnam experienced a dramatic drop in overall poverty during the 90s. However, the poverty reduction showed substantial variation across households, villages and regions. Using a multilevel model on panel data from the rural sample of the Vietnam Living Standard Measurement Survey we demonstrate the important role of villages in household poverty exit dynamics. We also show how an analysis of village-level random effects predictions can help targeting of policies to reduce poverty.     

Online hierarchical forecasting for power consumption data

This paper proposes a three-step approach to forecasting time series of electricity consumption at different levels of household aggregation. These series are linked by hierarchical constraints—global consumption is the sum of regional consumption, for example. First, benchmark forecasts are generated for all series using generalized additive models. Second, for each series, the aggregation algorithm ML-Poly, introduced by Gaillard, Stoltz, and van Erven in 2014, finds an optimal linear combination of the benchmarks. Finally, the forecasts are projected onto a coherent subspace to ensure that the final forecasts satisfy the hierarchical constraints. By minimizing a regret criterion, we show that the aggregation and projection steps improve the root mean square error of the forecasts. Our approach is tested on household electricity consumption data; experimental results suggest that successive aggregation and projection steps improve the benchmark forecasts at different levels of household aggregation.     

THE EXTENDED ECONOMETRIC INPUT–OUTPUT MODEL WITH HETEROGENEOUS HOUSEHOLD DEMAND SYSTEM

This paper proposes an extension to the regional econometric input–output model (REIM) [Conway, R.S. (1990) The Washington Projection and Simulation Model: A Regional Interindustry Econometric Model. International Regional Science Review, 13, 141–165; Israilevich, P.R., G.J.D. Hewings, M. Sonis and G.R. Schindler (1997) Forecasting Structural Change with a Regional Econometric Input–Output Model. Journal of Regional Science, 37, 565–590]. We integrate a demand system with age and income parameters into the REIM. The extended model thus addresses concerns about the effects of household heterogeneity. The initial testing is conducted with a model for the Chicago metropolitan area. First, using aggregate expenditure data by income and age groups, the almost ideal demand system with group fixed effects is constructed. Next, the estimated demand system is linked to the REIM to reflect long-term changes in the age and income distribution of households. The long-range simulation from the extended model takes into account structural changes in expenditure type stemming from changing demographic composition. The extended model further broadens the scope of impact analysis under various scenarios associated with age and income changes.     

Marriage Market,Parents’ Bargaining Powers,and Children's Nutrition and Education*

Test of resource pooling and test of effect of sex ratio in the marriage market on intrahousehold resource allocation are combined to test the unitary household model. The consistency condition between the two tests is derived to test the Nash household bargaining and Pareto‐efficient household models. I examine intrahousehold resource allocation to children's nutrition and education in Indonesia. For children's nutrition, the unitary household model is rejected in favour of the non‐unitary models. The results for investment in education are mixed. The decision‐making process may differ depending on the type of decision being made.     

INTRAHOUSEHOLD INEQUALITY AT DIFFERENT WELFARE LEVELS: ENERGY INTAKE AND ENERGY EXPENDITURE DATA FROM THE PHILIPPINES*

ABSTRACTS This paper investigates the relationship between intrahousehold inequality and levels of household welfare. Under certain conditions it is demonstrated — with both the unitary model of the household and with some collective models — that the relationship between household welfare and inequality within the household can have an inverted u-shape. Using two sets of calorie adequacy data from a sample of 455 households in the Philippines, a spline analysis is used to test the hypothesis that inequality within the household first increases and then decreases as per capita household total expenditure increases. The two sets of calorie adequacy data are based on repeated 24- hour recalls of dietary intake, and on calorie requirements that are unadjusted and then adjusted for individual activity patterns. Results indicate that once activity patterns are accounted for, calorie intake shortfalls are borne fairly equally within the household at all per capita household total expenditure levels.     

环境治理、技术进步与绿色经济发展绩效

Differences in Opportunities? Wage,Employment and House‐Price Effects on Migration*

Most empirical studies of individual migration choice analyse factors associated with out‐migration from an origin location. In contrast, we model the migration decision within the context of potential destinations, combining British panel data over the period 1992–2008 with other data sources. Contrary to earlier micro studies, we show that differences in house prices levels (but not growth) are important determinants of household migration for homeowners. Unemployed individuals respond to regional differences in expected individual wages, whereas the employed are more sensitive to employment opportunities. Our evidence is consistent with partners of heads of households being tied migrants.

REGIONAL ECONOMIC INTEGRATION AND ITS IMPACTS ON GROWTH, POVERTY, AND INCOME DISTRIBUTION: THE CASE OF INDONESIA

Indonesia continually tries to open its economy through free trade areas (FTAs) on bilateral, regional, and multilateral bases. This paper discusses the impacts of FTAs on the Indonesian economy, particularly for economic growth, poverty, and income distribution. By using a Global Computable General Equilibrium (GCGE) model, we conducted the simulation analysis by setting eighteen scenarios for the ongoing and potential FTAs of different frameworks. Indonesia is found to benefit from joining in FTAs, except for the FTA with India. It is also implied that FTAs increase rural household income at higher rates than they increase urban household income. Moreover, FTAs' impacts are more favorable for unskilled workers than for skilled ones, and also for relatively poor households more than for rich households, both in urban and rural areas. In brief, FTAs provide Indonesia with income redistribution effects.     

Household borrowing and metropolitan housing price dynamics – Empirical evidence from Helsinki

This article argues that, especially in the absence of sufficient direct data on credit constraints, it is reasonable to add a household debt variable in an empirical model studying housing price dynamics. This is because household borrowing is likely to reveal information regarding the credit constraints faced by households. Moreover, debt may also give information on expected income growth and interest rate movements. The aim of this study is to examine empirically if household borrowing data, indeed, is of importance in a dynamic housing price model. In line with the prior expectations, it is found that housing appreciation in the Helsinki Metropolitan area is Granger caused by the household debt-to-GDP ratio both in the short and in the long run. Causality from the housing market to credit, in turn, seems to run only through a cointegrating long-run relation. While the estimated long-run relation between housing prices, income and debt-to-GDP ratio appears to have remained stable through the sample period (1975Q1-2006Q2), the short-run dynamics changed somewhat due to the financial liberalization in the late 1980s. The stability of the long-run relation implies that the loan data are able to cater, at least to a notable extent, for the effect of the changes in Finnish households’ liquidity constraints on housing demand. In line with previous literature, it is also found that housing price adjustment is sluggish and includes notable backward-looking features.     

MATERNAL EDUCATION AND CHILD ATTAINMENT IN JAMAICA: TESTING THE BARGAINING POWER HYPOTHESIS†

In a bargaining model of household decision-making, any variable reflecting the outside opportunities of household members will influence household demand patterns. Mother's education has been found to be an important determinant of children's education and health outcomes. This paper argues that within a bargaining framework, mother's education may influence children's health and education by shifting bargaining power within the household. An empirical strategy is developed and applied to data on teenage grade attainment and school enrolment in Jamaica. The results support the bargaining power hypothesis, and imply a broader role for mother's education than has previously been considered.
