IMPACTS OF FOOD PRICES ON THE ECONOMY: SOCIAL ACCOUNTING MATRIX AND MICROSIMULATION APPROACH IN INDONESIA

This study investigated the impacts of increasing the prices of heavily protected food commodities in Indonesia on producer and consumer prices. It also evaluated the changes in household living expenses and poverty. The Indonesian Food Social Accounting Matrix was developed along with a price multiplier matrix–microsimulation approach that was used to analyze problems. Poor rural households were the most negatively affected by the increments in food prices. This result contrasted with the standard political argument stating that high rice prices will decrease poverty, particularly in rural areas where the poor live or work as farmers. Of all the food commodities observed, the changes in the rice prices had the most substantial impact on both producer and consumers price, as well as the households’ living cost, particularly low‐income households. Therefore, an increase of 25% in rice price will raise urban, rural, and national poverty levels by 0.13%, 0.10%, and 0.11%, respectively.     

Food Deserts and Real‐Estate‐Led Social Policy

Since the early 2000s in the United States, food deserts—neighborhoods in which households have limited geographic access to full‐service supermarkets or grocery stores— have become conceptually central in public policy research on food security. Analyzing this phenomenon from a ‘policy mobility’ perspective, this article traces the food desert's emergence in policy discourse, locating it within an entrepreneurial social policy paradigm that privileges real estate development over direct economic relief. In the context of property‐led anti‐poverty efforts, the identification and mapping of food deserts catalyzes a logic that leads to subsidy to grocery store development in low‐income areas (or ‘fresh food financing’), while at the same time officials are cutting programs such as the Supplemental Nutrition Assistance Program (food stamps), which directly supplements household food budgets. The article contributes to widening critical discussion of the food desert paradigm and the policy interventions with which it is associated. It calls on urban researchers and practitioners to reframe discussions of food access and nutrition around the shortage of basic income and a need for higher wage floors.     

Estimation of Poverty Transition Matrices with Noisy Data

This paper investigates measurement error biases in estimated poverty transition matrices. We compare transition matrices based on survey expenditure data to transition matrices based on measurement‐error‐free simulated expenditure. The simulation model uses estimates that correct for measurement error in expenditure. We find that time‐varying measurement error in expenditure data magnifies economic mobility. Roughly 45% of households initially in poverty at time t ? 1 are found to be out of poverty at time t using data from the Korean Labor and Income Panel Study. When measurement error is removed, this drops to between 26 and 31% of households initially in poverty. Copyright © 2016 John Wiley & Sons, Ltd.

Multiple Visits and Data Quality in Household Surveys

In order to increase data quality some household surveys visit the respondent households several times to estimate one measure of consumption. For example, in Ghanaian Living Standards Measurement surveys, households are visited up to 10 times over a period of 1 month. I find strong evidence for conditioning effects as a result of this approach: In the Ghanaian data the estimated level of consumption is a function of the number of prior visits, with consumption being highest in the earlier survey visits. Telescoping (perceiving events as being more recent than they are) or seasonality (first‐of‐the‐month effects) cannot explain the observed pattern. To study whether earlier or later survey visits are of higher quality, I employ a strategy based on Benford's law. Results suggest that the consumption data from earlier survey visits are of higher quality than data from later visits. The findings have implications for the value of additional visits in household surveys, and also shed light on possible measurement problems in high‐frequency panels. They add to a recent literature on measurement errors in consumption surveys (Beegle et al., 2012 , Gibson et al., 2015 ), and complement findings by Zwane et al. ( 2011 ) regarding the effect of surveys on subsequent behaviour.     

Moving up the Ladder or Stuck on the Bottom Rung? Homeownership as a Solution to Poverty in Urban South Africa

In the global South, policies providing property titles to low-income households are increasingly implemented as a solution to poverty. Integrating poor households into the capitalist economy using state-subsidized homeownership is intended to provide poor people with an asset that can be used in a productive manner. In this article the South African "housing subsidy system" is assessed using quantitative and qualitative data from in-depth research in a state-subsidized housing settlement in the city of Cape Town. The findings show that while state-subsidized property ownership provides long-term shelter and tenure security to low-income households, houses have mixed value as a financial asset. Although state-subsidized houses in South Africa are a financially tradable asset, transaction values are too low for low-income vendors to reach the next rung on the housing ladder, the township market. Furthermore, low-income homeowners are reticent to use their (typically primary) asset as collateral security for credit, and thus property ownership is not providing the financial returns that titling theories assume.     

Do stakeholder groups influence environmental management system development in the Dutch agri‐food sector?

This paper presents the results of a survey that included 492 companies in the Dutch agri‐food sector with respect to the influence of stakeholder groups on the companies' level of environmental management system (EMS) implementation. It is concluded that primary stakeholders (government, clients) are more relevant for EMS development than secondary stakeholders (such as environmental organizations). The results suggest that small and medium‐sized companies are able to accommodate to demands with respect to the implementation of internally oriented care systems (I‐EMSs). I‐EMSs focus at the single firm or location. In general, they are predominantly influenced by governmental and other ‘non‐commercial’ stakeholder groups. For the implementation of externally oriented EMSs (E‐EMSs), which focus on the supply chain and network, qualitative rather than quantitative relationship characteristics between companies and the government are important. Moreover, commercial stakeholder groups (such as suppliers, clients and competitors) influence E‐EMS levels significantly. Copyright © 2006 John Wiley & Sons, Ltd and ERP Environment.     

Regional Inequalities in Consumption Patterns: A Multilevel Approach to the Case of Italy

The main aim of this paper is to evaluate the disparities in the Italian regions on the demand side. In more detail, an attempt will be made to find if the consumption behaviour of Italian households is different in the regions. With this in mind, Istat's 2000 Italian Family Budget data set was analysed. The data in question, which were collected through a two‐stage sample over Italy's 20 regions, contains information regarding the expenses of approximately 23,000 households. In this analysis, both households and regions are considered as units: households are nested in the regions so that the basic data structure is hierarchical. In order to take this hierarchical structure into account, a multilevel model was used, making it possible for parameters to vary randomly from region to region. The model in question also made it possible to consider heterogeneity across different groups (regions), such as stochastic variation. First, regional inequalities were tested using a simple model in which households constituted the first level of analysis and were grouped according to their region (the second level). As a second step, and in order to investigate the interaction between geographical context and income distribution, another model was used. This was cross‐classified by income and regions. The most relevant results showed that there is wide fragmentation of consumption behaviour and, at the same time, various differentiated types of behaviour in the regions under analysis. These territorial differentials become clear from income class and items of consumption.

Bayes estimates of distance‐to‐market: transactions costs,cooperatives and milk‐market development in the Ethiopian highlands

Rationalizing non‐participation as a resource deficiency in the household, this paper identifies strategies for milk‐market development in the Ethiopian highlands. The additional amounts of covariates required for positive marketable surplus—‘distances‐to market’—are computed from a model in which production and sales are correlated; sales are left‐censored at some unobserved threshold; production efficiencies are heterogeneous; and the data are in the form of a panel. Incorporating these features into the modeling exercise is important because they are fundamental to the data‐generating environment. There are four reasons. First, because production and sales decisions are enacted within the same household, both decisions are affected by the same exogenous shocks, and production and sales are therefore likely to be correlated. Second, because selling involves time and time is arguably the most important resource available to a subsistence household, the minimum sales amount is not zero but, rather, some unobserved threshold that lies beyond zero. Third, the potential existence of heterogeneous abilities in management, ones that lie latent from the econometrician's perspective, suggest that production efficiencies should be permitted to vary across households. Fourth, we observe a single set of households during multiple visits in a single production year. The results convey clearly that institutional and production innovations alone are insufficient to encourage participation. Market‐precipitating innovation requires complementary inputs, especially improvements in human capital and reductions in risk. Copyright © 2008 John Wiley & Sons, Ltd.     

The collective bargaining of flexicurity: A case for sector‐level analysis? The Italian chemical and metalworking sectors compared

Although employment relations in Europe have long been seen as a factor of rigidity, limiting managerial discretion and adaptability, in the last 30 years, they have witnessed a trend towards decentralisation of collective bargaining and negotiations increasingly centred on flexibility–security trade‐offs between employers and employees. Research on the contribution of collective bargaining to the so‐called flexicurity has mostly focused on national‐level institutional arrangements. In this article, we contend that meso‐level differences need to feature more prominently in the debate. Our comparison of two sectors in the same country (chemicals and metalworking in Italy) shows that decentralisation has divergent effects on flexicurity issues depending in particular on differences in market structures and on depth of bargaining. The interplay between these two factors affects what we refer to as procedural security, which we view as important in ensuring sustainable trade‐offs between flexibility and security.

Geographic poverty traps? A micro model of consumption growth in rural China

How important are neighbourhood endowments of physical and human capital in explaining diverging fortunes over time for otherwise identical households in a developing rural economy? To answer this question we develop an estimable micro model of consumption growth allowing for constraints on factor mobility and externalities, whereby geographic capital can influence the productivity of a household's own capital. Our statistical test has considerable power in detecting geographic effects given that we control for latent heterogeneity in measured consumption growth rates at the micro level. We find robust evidence of geographic poverty traps in farm‐household panel data from post‐reform rural China. Our results strengthen the equity and efficiency case for public investment in lagging poor areas in this setting. Copyright © 2002 John Wiley & Sons, Ltd.

Accessibility of financial services and household consumption in China: Evidence from micro data

Access to finance has embraced by policymakers as an important tool for promoting inclusive development and achieving long-run financial security, while most studies provide macro-perspective evidence. Fewer yet, have taken into the additional role that digital finance may be playing. In this paper, we combine access to formal finance and digital finance into one framework. Based on the 2015 China Household Finance Survey data, we measure access to financial services from a microscopic perspective and construct a digital finance indicator. We then present evidence that both access to formal finance and digital finance significantly promote households’ consumption, and these effects are much larger for rural households and poorer households in China. Our finding also lend support to the conjecture that digital finance is more beneficial for inclusive development.     

Culture and Accountants' Perceptions of Environmental Reporting Practice

This paper seeks to investigate and interpret the possible link between culture and the perceptions of accountants on corporate environmental reporting practices (ENRPs) on a two‐country basis, i.e. between Malaysia and Australia. Using Hofstede's (1980) and Gray's (1988) cultural value framework, the paper employs a qualitative approach through interviews conducted with corporate accountants in publicly listed companies in Malaysia and Australia. It is revealed that ENRPs in both countries are influenced by cultural values, in particular collectivism, high uncertainty avoidance, uniformity, conservatism and secrecy. Despite the fact that types of cultural and sub‐cultural dimension pertaining to reporting practice in Malaysia and Australia are similar, mixed findings are found when compared with national cultural values (Hofstede, 1980) and sub‐cultural values (Gray, 1988). The consistencies of cultural dimensions found in ENRP in these two countries and the orientation of the practice across nations indicate a promising move towards standardization and harmonization of successful implementation of environmental accounting and reporting.

Assisted Self-help Housing in Mexico: Advocacy, (Micro)Finance and the Making of Markets

This article examines forms of housing finance that offer poor households opportunities for sourcing resources for construction work through non-mortgage microloans. In Mexico, these housing microfinance schemes have recently been incorporated into national housing policies. On a global level, the past 10 to 15 years have seen the emergence of institutional investment in microfinance. I reflect on these processes in this article by bringing critical accounts of financial inclusion in development studies and the debate on financialization within urban studies and beyond into dialogue. I combine micro- and macro-scale perspectives to examine how households become financial clients and how finance gains influence by expanding capitalist markets into the informal housing sector. This discussion is based on policy review and document analyses and an empirically grounded account of an assisted self-help housing case study. In the article I draw on three focal concepts—risk, debt and marketization—to highlight the ambivalences of the expanded access to finance for poor households engaged in self-organized building practices. These ambivalences emerge from the multiplicity of operational logics and motivations in the field of housing provision for the poor, and the profoundly conflicting rationalities of financial- and social-sector actors.

Inequality and catching-up under decreasing marginal impatience

This paper examines how endogenous time preference interacts with inequalities in economic development. We consider two distinct groups of households with intrinsic inequality (e.g., capitalists and workers), and show that (i) under decreasing marginal impatience (DMI), an unequal society may be preferable for poor households than an egalitarian one in which every household owns an equal share of asset; (ii) poor households tend to benefit more under DMI than CMI (constant marginal impatience) from positive shocks; (iii) inequality exhibits a sharp inverted-U shape as more people become rich, which should be good news for developing countries in catching up; and (iv) a tax on capital income reduces poor households’ income when the fraction of the rich is sufficiently small. We also examine immigration and discuss capital mobility.
