The objective was to increase earnings of the city of Prievidza from waste disposal fee by proactive communication – reminder (a letter) and leaflets with targeted framing. The quasi-experiment aims to find out which type of leaflet framing (an injunctive social norm or public good) causes the most effective change in the debtors' behaviour.

The article presents the results of a behavioural quasi-experiment, carried out on a local government level. The effectiveness of the intervention was tested in a quasi-experiment with the sample size 712, which is 35% of all waste disposal fee debtors in Prievidza.

The intervention that has proven to be the most effective was a reminder together with an injunctive social norm leaflet. It resulted in a 1.7 times higher probability for the debt to be paid. The results also indicate that a reminder is significantly more effective if targeted at debtors who only owe one payment–this group was three times more likely to pay their debt after being exposed to the intervention.

Public policy recommendation is to primarily target the group of debtors who owe one payment.

Another testing and replication of this experiment design is highly important. Nonetheless, the first testing (field quasi-experiment) shows the potential of using the notification as well as social norm framing. It also appears that self-governments should use notifications to primarily address debtors without a long history of non-payment.

Previous literature shows that activation requirements for welfare recipients reduce welfare participation. However, the effect of mandatory activation on welfare entry and exit rates has not been fully examined. In this article, we use a rich set of register data that covers the entire population of Stockholm to study how the introduction of activation programs aimed at unemployed welfare recipients in various city districts affects the probability of individuals entering and exiting social assistance (SA). Our results show that mandatory activation has no overall average effects on SA entry or SA exit. However, we do find a significant negative effect of mandatory activation on the SA entry rate for young individuals and for unmarried individuals without children. For unmarried individuals without children, we find a positive but statistically insignificant effect on the probability to leave SA. Thus, individuals with fewer family responsibilities seem to be more responsive to the reform.

This study aims to estimate the pass-through rate of the increases in the excise tax and TCF tax on tobacco in Vietnam. This study seeks to shed light on how the tax burden is split between consumers and producers and inform policy discussions in the country. Using panel micro-level data collected from three waves of a nationwide retailer's survey, this study provides an evidence-based pass-through estimation for tobacco tax in Vietnam and contributes to the understanding of tax policy on smoking and smoking-related issues.

Following increases in the excise tax and TCF tax on tobacco in 2019, the differential effect of the tax hike on the “treatment group” (domestic cigarettes) versus the “control group” (illicit cigarettes) using a difference-in-difference (DID) analysis has been studied. The study utilized unique longitudinal retailers’ data on cigarettes prices in Vietnam from 2018 to 2019 to estimate the tax pass-through rate for some of the most popular factory-made cigarette brands.

This study found evidence of an over-shifting of cigarette taxes on smokers. Specifically, it discovered that the tax increase is absorbed more by low-priced brand smokers compared to premium brand users due to (1) the limited increase in prices under a pure ad valorem system and (2) the way the Vietnamese currency is denominated. Additionally, there is evidence of cushioning to mitigate price shock on consumers as the real prices increase gradually over the period of one year after the tax change.

To the best of the authors’ knowledge, this study is the first to collect and analyze a unique panel micro-level data from three waves of a nationwide retailers’ survey, which captures the changes in marketing and pricing strategies of the tobacco industry in Vietnam before and after an increase in excise tax in 2019. The results of this study could be used as a reference for future policymakers in considering increasing taxes on tobacco.

The purpose of this study is to find out the effect of consumption tax on savings behavior especially on the people who are close to their retirement.

The authors analyze the response in spending and retirement saving using a difference-in-differences regression methodology. The authors use the year since the Public Provident Fund (PPF) enrollment date for each individual as a random assignment to identify the service tax policy's causal impact. Therefore, this variable is a continuous variable defined as an individual's age until the end of the restrictions when people can withdraw money from their retirement savings account PPF without any penalty. The treatment variable is the service tax shock (increase in service tax) that happened effective 1st April 2015.

The authors find a significant effect of a change in the service tax rate on individuals' spending and PPF saving behavior. On average, individuals lower their consumption by about 14% and increase their PPF savings by 16% in response to the increase in the service tax rate. The authors find substantial heterogeneity in effect across different types of individuals. The effect is more pronounced for people closer to their retirement and needy people (defined as individuals with low traditional savings account balances).

The authors studied the effect of consumption tax on one category of savings (PPF) only. There are other savings instruments available in India. The data for those were not available to us.

This paper not only throws light on the consumption and savings behaviour of the individuals, but will also help the policy maker for framing appropriate fiscal policy.

Using a unique and proprietary data from a large bank in India, the authors analyze the effect of a tax policy change on households' consumption and retirement savings behavior. The authors find that households reduce their consumption by 14% and increase their voluntary retirement savings (Public Provident Fund aka PPF) by 16% in response to an increase in the service tax policy. Individuals close to their retirement age (55 years of age and above) and without any withdrawal restrictions from their PPF account tend to reduce their expenditures more and save more. Individuals with financial constraints and withdrawal restrictions do not reduce their expenditures significantly. To the best of the authors’ knowledge no study was done on this.

This study aims to apply a proposed methodology for calculating spatial prices in a heterogeneous country setting such as India with limited price information. Based on the empirical evidence, the study plans to draw the spatial price map of India with different colours denoting states and districts with varying level of spatial prices.

This study shows that a procedure proposed by Lewbel (1989), based on the idea by Barten (1964) that household composition changes have “quasi-price effects”, can be used to estimate spatial prices in the absence of information on regional prices.

The evidence on spatial price differences in India, which is the most comprehensive to date because it goes down to district level, shows that the proposed procedure has considerable potential in future applications on other data sets with limited price information. The policy importance of the results is underlined by the sensitivity of the demand elasticities to the inclusion/omission of spatial price variation.

The study uses “pseudo unit values” based on household composition and demographic effects on demand as proxy for the missing price information. While the work of Atella et al. (2004) suggests that such proxies are accurate representations of true prices, nevertheless, they are proxies and the results should be treated with caution.

The evidence on spatial prices in India that point to a high degree of price heterogeneity between regions implies that welfare applications such as income distributional and poverty studies must take account of the price heterogeneity within the country. The implications extend beyond India to cross-country exercises such as the purchasing power parity calculations undertaken by the International Comparison Project.

This is one of the first studies that provide evidence on spatial price heterogeneity within a country without requiring regional price information. Methodologically, the paper builds on the suggestion of Lewbel (RES, 1989) in showing how the demographic effects on household expenditure pattern can be used to estimate spatial prices. The value of the contribution lies in the use that the estimated spatial prices can be put to in calculating inequality and poverty rates and in standard of living comparisons between regions in the country.

The purpose of this paper is to critically analyse the relevance of directly targeted poverty reduction programmes in Muslim countries by means of conditional cash transfers (CCTs). The paper analyses the best practices and lessons learnt to date and explores the practical issues to implement CCT poverty reduction programmes in Muslim countries.

The methodology is based on the qualitative assessment drawn from CCTs implementation in Muslim countries, namely Bangladesh, Indonesia, Pakistan and Turkey. The methodology also identifies the practical issues including the use of Islamic instruments to implement CCT poverty reduction programmes.

The analysis in Muslim countries suggests that CCT programmes have had a positive effect and that the costs are relatively affordable if implemented with appropriate programme designs. In many cases, there have been positive secondary effects over and above the primary goal of poverty reduction. The paper also argues that the concept of CCTs is in line with the underlying principle of Islam to eradicate poverty via cash distribution approach.

A decade long experience in some Muslim countries demonstrates that social cash transfers (including CCTs) have a significant impact on reducing poverty and vulnerability and promoting human development. Since none of CCT programmes in Muslim countries explore and integrate the potential of Islamic instruments (Zakat, Sadaqat, Awqaf and Qard Al-Hassan), it is timely for governments, multinational development institutions and non-profit organizations to utilize these instruments to tackling poverty.

This paper aims to understand the differing impacts of wealth distribution on human capital accumulation and skilled-unskilled labour generation under three educational paradigms as follows: private, public and a system of mixed education.

The authors use an overlapping generations model.

The wealth dynamics show that both in the private education system and public education system, there are two possible outcomes- stagnation and steady growth depending on the efficiency of the education system, skill premium and other parameters. The choice of the education system through voting is discussed. It is found that skilled workers would always vote for private education whilst unskilled workers vote for private education if public education expenditure of the economy is low.

The study is subject to several limitations. This paper considers the rate of interest and wage rate to be exogenously given, and thus ignores the general equilibrium effects. The authors do not consider the labour-leisure choice. The introduction of labour leisure choice in the model would alter many of the results. The authors do not consider heterogeneous ability across individuals. The analysis of the differential efficiency of the different education systems needs further, rigorous research. Also, this paper does not consider other occupations such as entrepreneurship and self-employment. This paper considers the labour demand function to be perfectly elastic, and hence, does not consider any demand constraint. What happens if bequests are taxed? What happens if parents are not altruistic? These questions may be addressed in future research.

If the proportion of tax paying skilled labour is low in any country, pure public education may not be able to generate sustained human capital growth. For countries with a sufficiently large proportion of skilled labour, the public education system would be successful. On the other hand, if skill premium is low or the education system is poorly managed private education system may fail too.

Whilst investigating the effects of public vs private education on growth and development in the presence of unequal wealth distribution, The authors have tried to address a few questions. First, why the public education system has been successful in skill accumulation in developed countries whilst it has failed to do so in less developed countries? Second, why do some countries with mostly privately run educational institutions perform much better in human capital production whilst others do not? Third, in an economy with unequal wealth distribution, what are the factors that result in public or private education as a voting equilibrium outcome?

The purpose of this paper is to show how the taxation effect on cross-state smuggling can be a valid instrumental variable for lagged and future consumption together with the local price series.

On the same grounds, the authors raise the question using the rational-addiction model by noticing that the neighboring price differentials really capture the possible smuggling or bootlegging effects.

Moreover, the authors look into the extended model to test the key condition that the expected future financial consequences will affect the current consumptions.

This supports the rational-addiction model, which can be used to plan the taxation for the forward-looking consumptions.

The purpose of this study is to assess the impact of credit constraints on agricultural labour productivity as well as the impact of credit constraints and agricultural labour productivity on rural households' consumption in Ghana.

This study uses the Ghana Living Standard Survey round six (GLSS 6) as the main source of data, which happens to be one of the most comprehensive household datasets in Ghana. Quantitative estimation techniques (namely: Endogenous Switching Regression and Two Stage Least Squares) are used to address possible endogeneity and selection into credit markets.

First, large households are prone to credit constraints while age (experience) and compliance with extension advice reduce credit constraints. Second, the determinants of agricultural labour productivity for both constrained and unconstrained households are age, sex, farm equipment, herbicide and farm size. Third, household size, education and livestock rearing influence agricultural labour productivity of constrained households. Fourth, credit constraints, irrespective of how they are measured, impede agricultural labour productivity while access to credit fosters labour productivity. Lastly, credit constraints robustly reduce consumption while agricultural labour productivity strongly enhances rural households' consumption.

The first contribution is that, unlike most previous studies, we do not focus on the widely used measure of productivity – output per unit land, but on agriculture labour productivity in particular. Secondly, unlike most previous studies which examine the effect of credit constraints either on productivity alone or consumption alone, our study examines the impact of credit constraints on both. Thirdly, unlike the existing literature which uses one or two measures of credit constraints, we use a wide range of measures of credit constraints – seven different measures of credit constraints. Lastly, our empirical strategy solves at least two critical econometric problems – sample selection bias and endogeneity.

The authors develop and validate a conceptual model, the retirement engagement model (REM), to understand the relationships between behavioral engagement (retirement information search), cognitive factors and engagement (e.g. beliefs and financial knowledge), emotional engagement (e.g. anxiety), and socio-demographic factors. Approach: The authors derive the REM through a three-step procedure: (1) an extensive literature review, (2) interactive feedback sessions with experts to confirm the model's academic and managerial relevance, and (3) an empirical test of the REM with field data (N = 583). The authors use a partial least squares (PLS) structural equation model and examine heterogeneity through a finite mixture model.

Around the globe, people are insufficiently engaged with retirement planning. The customer engagement literature offers rich insights into antecedents, outcomes, and barriers to engagement. However, customer engagement literature lacks insights into cognitive, emotional and behavioral factors that drive engagement in retirement planning, a utilitarian service context, which is important for financial well-being.

Beliefs such as perceived susceptibility, severity, benefits, barriers, and self-efficacy, together with trust and retirement anxiety, explain people's search for pension information. These factors can be used to define three clear, actionable segments of consumers.

The findings advance the customer engagement and transformative service research literature by generating insights on engagement with retirement planning, a utilitarian rather than hedonic service context that is especially relevant for financial well-being. The findings inform managerial practice and emphasize the relevance of including cognitive and emotional engagement factors that trigger behavioral engagement. The REM can help to improve pension communication. For example, the results indicate that marketers should stress the benefits of, rather than the barriers to, acquiring information.
