Estimation of the two-tiered stochastic frontier model with the scaling property

The two-tiered stochastic frontier model has enjoyed success across a range of application domains where it is believed that incomplete information on both sides of the market leads to surplus which buyers and sellers can extract. Currently, this model is hindered by the fact that estimation relies on very restrictive distributional assumptions on the behavior of incomplete information on both sides of the market. However, this reliance on specific parametric distributional assumptions can be eschewed if the scaling property is invoked. The scaling property has been well studied in the stochastic frontier literature, but as of yet, has not been used in the two-tier frontier setting.     

The Distributional Effects of Public Expenditure

It is commonly agreed that economic policies, including budgetary policies, can have potentially strong distributional effects. Traditional economic analysis held that economic policies affected the income distribution primarily through their impact on the rate of growth. More recently, it has come to be recognised that qualitative aspects of economic growth are probably more important than the rate of growth itself. While recent research has confirmed the potential role of expenditure policies as a redistributive tool, it has also shown that redistribution does not necessarily have to come at the expense of economic growth and efficiency. Although there are substantial analytical and technical problems to be faced in the design of equitable and cost-effective public expenditure programmes, unfavourable distributional outcomes of these programmes can usually be traced more to political and institutional pressures than to purely technical factors.

INTEGRATING A HOUSEHOLD DEMAND SYSTEM IN THE INPUT–OUTPUT FRAMEWORK. METHODOLOGICAL ASPECTS AND MODELLING IMPLICATIONS

In this paper we argue that an accurate representation of household consumption behaviour is central to the analysis and comparison of policy interventions addressing sustainable consumption. Therefore, we propose to extend an input–output model with a specific household consumption model, at the core of which is a system of equations explaining the allocation of the households' overall expenditure across different purposes, such as buying food, the consumption of fuel for heating or electricity for cooling, education of children or travelling in terms of total expenditure and relative prices. This paper shows that the integration of a specific module for household consumption in a standard input–output model is an improvement for the analysis of the policies aimed at altering consumer behaviour.     

住房价格、社会保障支出和居民消费——基于面板门槛模型的实证分析

党的十九大报告提出了改善住房制度、加强社会保障和完善消费体制等一系列要求，这些热点问题之间不是孤立的，而是存在着内在的联系。为此，基于不确定性视角，将社会保障支出水平纳入分析框架研究发现，住房价格上涨通过社会保障支出对居民消费产生正向影响，与原有住房价格通过收入视角对居民消费产生的效应相叠加，使住房价格对居民消费产生的总效应呈现非线性关系。在此基础上，以地方政府社会保障支出水平作为门槛变量，建立关于房价和居民消费率关系的面板门槛模型，以我国2007—2015年省际面板数据为样本进行实证分析，结果表明：社会保障水平的变化使得住房价格对于居民消费率的影响存在显著的单门槛效应。当社会保障支出水平小于其门槛值时，住房价格上涨对居民消费率有较强的抑制效应，两者之间呈现显著的负相关关系；当社会保障水平超过门槛值后，住房价格上涨对居民消费率的抑制效应明显减弱。     

Distributional Effects of a Continuous Treatment with an Application on Intergenerational Mobility

This paper considers the effect of a continuous treatment on the entire distribution of outcomes after adjusting for differences in the distribution of covariates across different levels of the treatment. Our methodology encompasses dose-response functions, counterfactual distributions, and ‘distributional policy effects’ depending on the assumptions invoked by the researcher. We propose a three-step estimator that consists of (i) estimating the distribution of the outcome conditional on the treatment and other covariates using quantile regression; (ii) for each value of the treatment, averaging over a counterfactual distribution of the covariates holding the treatment fixed; (iii) converting the resulting counterfactual distribution into parameters of interest that are easy to interpret. We show that our estimators converge uniformly to Gaussian processes and that the empirical bootstrap can be used to conduct uniformly valid inference across a range of values of the treatment. We use our method to study intergenerational income mobility where we consider effects of parents’ income on features of their child's income distribution such as (i) the fraction of children with income below the poverty line; (ii) the variance of child's income; and (iii) the inter-quantile range of child's income–all as a function of parents’ income.     

二元经济结构视角下民生性财政支出与消费关系研究

习近平总书记指出目前中国正处于新发展阶段,我们要加快构建新发展格局,扩大内需,刺激消费。在此背景下,论文依托中国2013-2019年31个省相关的统计数据,利用个体固定效应模型分析民生性财政支出各组成部分对城乡居民消费水平的共性和差异化影响。研究表明,环境保护和住房保障支出对于城乡居民消费水平都没有显著的作用,而教育支出、社会保障和就业这两项支出对城镇居民消费水平的作用较为显著,医疗卫生支出对农村居民来说是正向的。     

Forecasting GDP growth with NIPA aggregates: In search of core GDP

In addition to GDP, which is measured using expenditure data, the U.S. national income and product accounts (NIPAs) provide a variety of measures of economic activity, including gross domestic income and other aggregates that exclude one or more of the components that make up GDP. Similarly to the way in which economists have attempted to use core inflation—which excludes volatile energy and food prices—to predict headline inflation, the omission of GDP components may be useful in extracting a signal as to where GDP is going. We investigate the extent to which these NIPA aggregates constitute “core GDP.” In an out-of-sample forecasting exercise using a novel real-time dataset of NIPA aggregates, we find that consumption growth and the growth of GDP excluding inventories and trade have historically outperformed a canonical univariate benchmark for forecasting GDP growth, suggesting that these are promising measures of core GDP growth.     

Regression over Timescale Decompositions: A Sampling Analysis of Distributional Properties

In two previous papers, Ramsey and Lampart demonstrated that regression analyses between timescale decompositions provided important insight into the properties of economic relationships. The idea in those papers was that the relationship between any two variables, say consumption and income, was the union of the individual relationships between consumption and income at each timescale and that the regression relationship might, differ across timescales. This paper is dedicated to discovering the approximate distributional properties of the regression estimators and of the residuals in the context of such models. Sampling procedures are used to verify the distributional properties of the regression estimators at each timescale and those of the residuals. This analysis is necessary to provide the appropriate distributional information required to specify tests of hypotheses and confidence intervals.     

Technical Change in the Private Consumption Converter

The analysis of technological change is centered on the study of the evolution of technical coefficients in the input–output table. Complementary to this analysis, the household consumption expenditure matrix, relating consumption by commodities to consumption by purpose or by function, also incorporates some other aspects of technological change. Thus, the evolution in time of the coefficients of this consumption expenditure matrix will portray technological processes, implying substitutions between commodities to satisfy the different functions The substitution between consumption expenditure by functions is also to be taken into consideration, because it can influence, together with technological change, the use of commodities in the final demand. For Switzerland, a 1980–89 time series of household consumption expenditure matrices with 37 commodities and 58 functional consumption categories has been estimated using data from consumer expenditure surveys. In this paper, instruments generally applied to the analysis of changes in input–output technical coefficients are extended to these matrices, including methods that deal with biproportional processes of substitution.     

What do women want? Female suffrage and the size of government

The economic literature has attributed part of the increase in government expenditure over the 20th century to female voting. This is puzzling, considering that the political science literature has documented that women tended to be more conservative than men over the first half of the 20th century. We argue that the current estimates of this relationship are afflicted by endogeneity bias. Using data for 46 countries and a novel set of instruments related to the diffusion of female suffrage across the globe, we find that, on average, the introduction of female suffrage did not increase either social expenditures or total government expenditure.     

Scaling of HIS in a global context: Same,same, but different

Scaling of information systems is a field of research with growing importance. This paper presents the story of scaling of an artifact (called District Health Information Software — DHIS) and associated principles and practices around a health information system that has taken place over 15 years, both within and between multiple developing countries. Through the lens of the story of the artifact over its trajectory of development and implementation in multiple contexts and time, we develop insights that challenge traditional thinking around scaling. Scaling is not about constant gains and expansion, as is often assumed, but involves a dichotomy of losses and gains, associated with each step or translation in its process of movement. We draw upon Latour's insights on circulating references to analyze this dichotomy of loss and gains, conceptualizing the process as circulating translations. We contribute to the technology transfer literature in arguing that the process of transfer is not about a “parachuting” from point A to B, or a “design from nowhere” but something which occurs in a series of small steps, where with each step new socio-technical configurations are created which not only shape subsequent steps, but also redefine the content of the artifact. In this way, we are in line with findings from the social studies of technology, but differ in that our artifact of study – software – is more “virtually immaterial” than machines which had been primarily earlier objects of study. This property of software, coupled with growth of web-based and mobile infrastructure, allows relative ease of circulation across contexts, where it gets redefined and embedded at the same time at the interconnected levels of the global and local. We conceptualize this process of global scaling as being “same, same, but different”. We discuss both the characteristics of this process of global scaling, and the channels and mechanisms through which it takes place. Four overlapping conditions that shape this process include the software itself, the infrastructure, institutional practices, and ideas — these form the basis for a general framework to understand global scaling of health information systems. Empirically, the story of DHIS is told from its birth in the mid-nineties in South Africa developed on a Microsoft platform to its transformation to a web-based platform, built using Java based open-source frameworks, and now moving through multiple countries. We focus on these dynamics primarily within three countries namely India, Sierra Leone and Kenya.     

House prices, wealth effects, and the Singapore macroeconomy

This paper examines the effect housing wealth has upon aggregate consumption in Singapore. While past research has focused only on changes in private housing wealth, the residential market in Singapore is dominated by the public housing sector. The massive public housing segment can generate potentially different wealth effects from standard private housing markets given the former’s unique institutional features. In particular, public housing owners who sell their units at market rates can repurchase a public flat at subsidized prices whereas private homeowners typically cannot. We estimate the link between consumption expenditure and both private and public housing wealth using a VARX approach for the Q1:1990–Q4:2002 period. We find that changes in private house prices have no significant effect on aggregate consumption. In contrast, public housing wealth effects are larger and more persistent.     

Social expenditure cyclicality: New time-varying evidence in developing economies

This paper provides a novel dataset of time-varying measures of cyclicality in social spending for an unbalanced panel of forty-five developing economies from 1982 to 2012. We focus on four categories of government social expenditure: health, social protection, pensions, and education. We find that in developing countries social spending has been acyclical over time, with the exception of spending on pensions. However, sample averages hide marked heterogeneity across countries, with many individually showing procyclical behavior in different social spending categories. The use of time-varying measures of social spending cyclicality overcomes the major limitation of previous studies in assessing the drivers of fiscal cyclicality that rely solely on cross-country regressions and, therefore, cannot account for country-specific as well as global factors. Using weighted least squares regressions, we find that the degree of social spending (pro)cyclicality is negatively associated with financial deepening, the level of economic development, trade openness, government size, and political constraints on the executive.     

Impact of Changes in Consumer Preferences on Sectoral Labour Reallocation: Evidence from the Italian Economy

This study empirically investigates the impact of changes in consumer preferences on labour reallocation across the Italian economic sectors. For this purpose, coherent sectoral time series of consumer preferences and labour units are constructed from Italian national accounts and consumption expenditure data. In line with recent firm‐level evidence, empirical findings indicate a positive and significant effect of preference changes on labour reallocation. Results are robust to several econometric specifications, different procedures to elicit preference changes, as well as the introduction of time‐varying price coefficient and sector‐specific effects of total consumption expenditure.     

Nonparametric estimation of the determinants of inefficiency

We consider the benchmark stochastic frontier model where inefficiency is directly influenced by observable determinants. In this setting, we estimate the stochastic frontier and the conditional mean of inefficiency without imposing any distributional assumptions. To do so we cast this model in the partly linear regression framework for the conditional mean. We provide a test of correct parametric specification of the scaling function. An empirical example is also provided to illustrate the practical value of the methods described here.     

Ordering utility functions based on mean-seeking behavior1

We consider utility function partial orderings to predict comparative portfolio features with two risky assets. No utility ordering can predict comparative holdings of the riskier asset for any reasonable definition of the latter. We thus reinterpret results of Arrow-Pratt and Ross as predicting comparative mean-seeking behavior. We also present a stronger utility ordering which predicts comparative portfolio means with no joint distribution restrictions. Thus we present a progression of contexts, with successively more relaxed distributional restrictions and hence successively stronger restrictions on utility function pairs, in which comparative mean-seeking behavior (not comparative risk avoidance) is predictable.

Toward a Theory of Activist-Driven Responsible Innovation: How Activists Pressure Firms to Adopt More Responsible Practices

Accounts of stakeholder influence on corporate social responsibility (CSR), situated in the CSR domain, have recognized that activists mitigate information asymmetries between firms and consumers. However, depictions of activists as information disseminators do not explain how they perform their quintessential role – pressuring resistant firms to engage in responsible innovation that emphasizes the creation of socioenvironmental value. Drawing from social movement theory that identifies claims as the instrument of such pressure, we examine four activist organizations’ use of claims across six campaigns to drive firms to adopt more socially and environmentally responsible practices, a form of responsible innovation. Our core contribution is an empirically grounded theory of activist-driven responsible innovation (ARI) that proposes how activists use claims to drive firms to engage in responsible innovation, as well as how features of the two sides may shape this outcome. Our ARI theory primarily enriches accounts of stakeholder influence on corporate social responsibility in the CSR domain and, in doing so, secondarily enriches accounts of the influence of activists’ claims on firms in the social movement domain. These contributions also speak to the resolution of grand challenges, a core interest of the special issue.     

Efficient inequality: differential allocation in the local public sector

This paper examines the consequences for social efficiency if the locally provided public input can be differentially allocated among residents. We derive the distributional efficiency condition, which is the distribution of public inputs that maximizes within-city gains from trade. Differential allocation also causes modifications to the standard (Samuelsonian) allocative efficiency condition. Additionally, we explore the consequences of differential allocation for the median voter model. Standard empirical voter models are seriously flawed because they fail to distinguish final public output production from either individual demand or the distribution of publicly provided inputs. Finally, we derive the club sharing efficiency condition.
