How Does Neopatrimonialism Affect the African State? The Case of Tax Collection in Zambia

Following the neopatrimonialism paradigm, it can be hypothesised that in African states informal politics of the rulers infringe on the collection of taxes and in turn reduce state revenues. This article tests this proposition for the case of Zambia. The main finding is that there is no linear correlation between a neopatrimonial system and the collection of taxes. Neopatrimonial continuity in the country is evidenced by three factors; the concentration of political power, the award of personal favours and the misuse of state resources. De-spite this continuity, the revenue performance has increased considerably with the crea-tion of the semi-autonomous Zambia Revenue Authority. This demonstrates that the effect of neopatrimonialism on public policy in the African state is highly context-specific and dependent on the interaction with additional variables. Donor pressure has been the most important in the Zambian case. In order to apply neopatrimonialism for further empirical work on public policy in the African state, these additional variables have to be incorpo-rated into the analysis.Neopatrimonialism, collection of revenue, tax systems, Zambia, African state, donors

Stagnation of a “Miracle”:Botswana’s Governance Record Revisited

Botswana has been dubbed an “African miracle.” The country has been praised not only for maintaining a multiparty system and high growth rates since independence but also for its good governance record. In contrast to other African countries, the extent of neopatrimonialism, which runs counter to good governance, is said to be low. This article aims to a) precisely assess Botswana’s neopatrimonial profile and b) put forward explanations for the comparatively low level of neopatrimonialism and for the recent “stagnation of a miracle.” The paper finds that there have always been neopatrimonial tendencies in Botswana, though they have been largely overlooked by mainstream analyses. The crucial difference is the limited nature of these tendencies relative to other African countries. This can be attributed to the independence period, characterized by the homogeneity of political, economic, and administrative interests in safeguarding private property rights through a “strong” rational-legal state, that is, by limiting neopatrimonialism. Financed by massive revenues stemming from diamonds, the Southern African Customs Union (SACU), and the Bank of Botswana, the government of the Botswana Democratic Party (BDP) was able to secure its reign through the provision of public goods and limited neopatrimonial exchange relations. However, due to decreasing electoral dominance and elite cohesion, the ruling party is now reverting to some neopatrimonial and authoritarian means in order to safeguard its rule.neopatrimonialism, corruption, governance, institutions, interests, development, Botswana

Measuring the Capability to Raise Revenue Process and Output Dimensions and Their Application to the Zambia Revenue Authority

The worldwide diffusion of the good governance agenda and new public management has triggered a renewed focus on state capability and, more specifically, on the capability to raise revenue in developing countries. However, the analytical tools for a comprehensive understanding of the capability to raise revenue remain underdeveloped. This article aims at filling this gap and presents a model consisting of the three process dimensions ‘information collection and processing’, ‘merit orientation’ and ‘administrative accountability’. ‘Revenue performance’ constitutes the fourth capability dimension which assesses tax administration’s output. This model is applied to the case of the Zambia Revenue Authority. The dimensions prove to be valuable not only for assessing the how much but also the how of collecting taxes. They can be a useful tool for future comparative analyses of tax administrations’ capabilities in developing countries.capability to raise revenue, revenue authority, tax administration, Zambia

Asymmetric adaptations to energy price changes

The effectiveness of policies to reduce the use of energy depend on the elasticity of substitution between the various inputs and on the rate of technological progress. This paper presents a theoretical model emphasising energy investments’ characteristics of uncertainty and irreversibility that result in testable hypotheses concerning the relative values of substitution parameters and rates of technological change in periods of high and increasing energy prices and in periods of low prices. Estimation results for a panel of sectors of the Dutch economy show that the elasticity of substitution between energy and other inputs is low in periods of low energy prices, whereas it is significantly higher in the preceding period of high and increasing energy prices. Furthermore, energy-saving technological progress in periods of high and increasing energy prices is also significantly higher than if energy prices are low and falling. The regression results suggest that, due this asymmetric response of firms to changes in energy prices, taxing energy in the current period of low energy prices will not yield substantial reductions in energy use of Dutch industry.

The Fixed-Effects Zero-Inflated Poisson Model with an Application to Health Care Utilization

Response variables that are scored as counts and that present a large number of zeros often arise in quantitative health care analysis. We define a zero-in flated Poisson model with fixed-effects in both of its equations to identify respondent and health-related characteristics associated with health care demand. This is a new model that is proposed to model count measures of health care utilization and account for the panel structure of the data. Parameter estimation is achieved by conditional maximum likelihood. An application of the new model is implemented using micro level data from the 2004-2006 Survey of Health, Ageing and Retirement in Europe (SHARE), and compared to existing panel data models for count data. Results show that separately controlling for whether outcomes are zero or positive in one of the two years does make a difference for counts with a larger number of zeros.Count Data;Zero-In ated Poisson Model;Fixed-effects;SHARE

Mode and Context Effects of Measuring Household Assets

Differences in answers in Internet and traditional surveys can be due to selection, mode, or context effects. We exploit unique experimental data to analyze mode and context effects controlling for arbitrary selection. The Health and Retirement Study (HRS) surveys a random sample of the US 50+ population, with CAPI or CATI core interviews once every two years. In 2003 and 2005, random samples were drawn from HRS respondents in 2002 and 2004 willing and able to participate in an Internet interview. Comparing core and Internet survey answers of the same people, we analyze mode and context effects, controlling for selection. We focus on household assets, for which mode effects in Internet surveys have rarely been studied. We find some large differences between the first Internet survey and the other three surveys which we interpret as a context and question wording effect rather than a pure mode effect.Internet surveys;CAPI;CATI;portfolio choice

A Test for Anchoring and Yea-Saying in Experimental Consumption Data

In the experimental module of the AHEAD 1995 data, the sample is randomly split into respondents who get an open-ended question on the amount of total family consumption - with follow-up unfolding brackets (of the form: is consumption $X or more?) for those who answer don't know' or refuse' - and respondents who are immediately directed to unfolding brackets. In both cases, the entry point of the unfolding bracket sequence is randomized. These data are used to develop a nonparametric test for whether people make mistakes in answering the first bracket question, allowing for any type of selection into answering the open-ended question or not. Two well-known types of mistakes are considered: anchoring and yea-saying (or acquiescence). While the literature provides ample evidence that the entry point in the first bracket question serves as an anchor for follow-up bracket questions, it is less clear whether the answers to the first bracket question are already affected by anchoring. We reject the joint hypothesis of no anchoring and no yea-saying at the entry point. Once yea-saying is taken into account
