The political economy of constitutional choice: a study of the 2005 Kenyan constitutional referendum

Recent studies of the linkages between the wealth of nations and the institutions of governance suggest that concentrating political power in a monarchy or a ruling coalition impedes economic growth and, moreover, that while power-diffusing reforms can enhance the wellbeing of society in general, opposition by groups benefiting from the status quo is predictable. In November 2005, Kenyans rejected a proposed constitution that, despite promises made by their new chief executive, would not have lessened the powers of the presidency. Using a unique, constituency-level dataset on the referendum vote, we estimate a model of the demand for power diffusion and find that ethnic groups’ voting decisions are influenced by their expected gains and losses from constitutional change. The results also highlight the importance of ethnic divisions in hindering the power-diffusion process, and thus establish a channel through which ethnic fragmentation adversely impacts economic development.

Constitutional design for a rent-seeking society: Voting rule choice

If rent-seeking costs are considered in addition to, and separate from, external costs and decision costs in Buchanan and Tullock's economic theory of constitutions, total interdependence costs may have multiple local minima close to the decision-making extremes. As a result, the global minimum, which gives the optimal decision rule, may be much closer to “unanimity rule” or “individual rule” than to “simple majority rule”. Further, the comparison of the minimum total interdependence costs for the public sector with those for the private sector would only justify a smaller scope and size for the public sector than would be the case if rent-seeking costs were ignored. Finally, systematic variation in rent-seeking cost could account for dramatic regime shifts between dictatorship and democracy.     

Using observational analysis of multiple sclerosis relapse to design outcomes-based contracts for disease-modifying drugs: a feasibility assessment

Abstract

Objective:

To assess predictors and costs of multiple sclerosis (MS) relapse, a potential outcome measure in payer-manufacturer risk-sharing agreements for disease-modifying drugs (DMDs).

Methods:

A retrospective cohort analysis of medical/pharmacy claims was used. Study patients had ≥1 DMD (interferon beta, glatiramer, natalizumab) claim, without DMD claims in a 6-month pre-period before DMD initiation; were aged 18–64 years and continuously enrolled from the pre-period through a 24-month post-period; and had ≥2 MS medical claims during the 30-month study period. Post-period relapse cohorts included: (1) severe (hospitalization with MS diagnosis); (2) moderate (outpatient services including intravenous methylprednisolone); and (3) none. Poisson regression modeled severe relapse frequency, logistic regression modeled ≥1 severe relapse, and generalized linear modeling predicted healthcare costs. Tested predictors included demographics, insurance type, index DMD, pre-period health status, and DMD medication possession ratio (MPR).

Results:

Severe relapse was experienced by 14.5% and moderate relapse by 13.8% of 2291 patients. In logistic regression, severe relapse was predicted by plan type; age (odds ratio [OR]?=?1.018, 95% confidence interval [CI]?=?1.005–1.031); pre-period Charlson Comorbidity Index (OR?=?1.307, 95% CI?=?1.166–1.464); pre-period proxy measure indicating impaired activities of daily living (OR?=?1.470, 95% CI?=?1.134–1.905); pre-period MS hospitalization (OR?=?2.174, 95% CI?=?1.537–3.074); and DMD non-adherence (MPR OR?=?0.101, 95% CI?=?0.068–0.151). Poisson regression results were similar. Predicted mean [standard deviation] all-cause healthcare expenditures were tripled for patients with severe compared with moderate relapse ($48,173 [$8665] and $13,334 [$1929], respectively).

Limitations:

Commercially insured patients from a single payer; use may have been inconsistent with approved indications; proxy relapse measure may have misclassified patients.

Conclusions:

Severe MS relapses requiring hospitalization, although affecting less than 15% of patients initiating DMD treatment, are associated with high medical costs. The only actionable predictor of severe relapse identified in observational analysis was MPR, raising questions about the feasibility of using observational data to guide outcomes-based contracting.     

Direct democracy in Australia: Voter behavior in the choice between constitutional monarchy and a republic

Opinion polls conducted throughout the 1990s indicate most Australians favor a republic. A referendum making that constitutional change, however, was defeated. This paper investigates whether voters employ a loss-minimization rule, as opposed to a value-maximization rule, when making political decisions. Based on the predictions of each rule, political strategies are devised and compared to the official arguments employed by republicans and monarchists during the period preceding the vote. Empirical research relates voting outcomes at the individual voter level to influences that are likely to be correlated with political risk aversion. The results are consistent with the conclusion that voters do not employ value-maximization rules.

Regulation and administered contracts revisited: Lessons from transaction-cost economics for public utility regulation

This article reexamines the administered contracts approach to regulation in light of recent empirical research that establishes the importance of transaction-costs in the organizational choice and design decisions. After reviewing the fundamentals of transaction cost reasoning and the franchise bidding-versus-regulation debate, the study surveys the empirical literature on franchise bidding, contracting, and vertical integration. The implications of transaction-cost theories for current policies toward pubic utility regulation and deregulation are also addressed.We would like to thank Michael Crew, Victor Goldberg, Mark Lowry, Claude Menard, and Roger Sherman for helpful comments.     

Social preferences and public economics: Mechanism design when social preferences depend on incentives

Social preferences such as altruism, reciprocity, intrinsic motivation and a desire to uphold ethical norms are essential to good government, often facilitating socially desirable allocations that would be unattainable by incentives that appeal solely to self-interest. But experimental and other evidence indicates that conventional economic incentives and social preferences may be either complements or substitutes, explicit incentives crowding in or crowding out social preferences. We investigate the design of optimal incentives to contribute to a public good under these effects would make either more or less use of explicit incentives, by comparison to a naive planner who assumes they are absent.     

Optimal pricing and capacity choice for a public service under risk of interruption

We develop rules for pricing and capacity choice for an interruptible service that recognize the interdependence between consumers’ perceptions of system reliability and their market behavior. Consumers post ex ante demands, based on their expectations on aggregate demand. Posted demands are met if ex post supply capacity is sufficient. However, if supply is inadequate all ex ante demands are proportionally interrupted. Consumers’ expectations of aggregate demand are assumed to be rational. Under reasonable values for the consumer’s degrees of relative risk aversion and prudence, demand is decreasing in supply reliability. We derive operational expressions for the optimal pricing rule and the capacity expansion rule. We show that the optimal price under uncertainty consists of the optimal price under certainty plus a markup that positively depends on the degrees of relative risk aversion, relative prudence and system reliability. We also show that any reliability enhancing investment—though lowering the operating surplus of the public utility—is socially desirable as long as it covers the cost of investment.     

Strategy-proof and individually rational social choice functions for public good economies: A note

Summary. Serizawa [3] characterized the set of strategy-proof, individually rational, no exploitative, and non-bossy social choice functions in economies with pure public goods. He left an open question whether non-bossiness is necessary for his characterization. We will prove that non-bossiness is implied by the other three axioms in his characterization.

The public value of improving a weather forecasting system in Korea: a choice experiment study

The Korean government plans to improve the quality of its weather forecasting system in order to increase its public utility. The benefits arising from the implementation of this plan should be measured. To this end, this study applies a choice experiment to four attributes: the update frequency of both short- and medium-range forecasts, and the accuracy of both. A survey of 1000 randomly selected households was undertaken in Korea. In the study results, the marginal willingness-to-pays, respectively, for one more update of the short-range forecast per day, for a 1% increase in the accuracy of the short-range forecast, for changing the update frequency of the medium-range forecast from once a day (reference level) to twice a day, and for a 1% increase in the accuracy of the medium-range forecast as a result of improving the weather forecast service were estimated to be KRW 499.3 (USD 0.45), 108.3 (0.10), 346.5 (0.31), and 80.9 (0.07) per household per month. The findings can provide policy-makers with useful information for both evaluating and planning improvements in the weather forecasting system.     

Putting all one's eggs in one basket: Relational contracts and the management of local public services

French municipalities often contract out the provision of local public services to private companies, and regularly choose the same private operator for a range of different services. We develop a model of relational contracts that shows how this strategy may lead to better performance at lower cost for public authorities. We test the implication of our model using an original database of the contractual choices made by 5000 French local public authorities in the years 2001, 2004 and 2008.     

Estimation of the public benefits of urban water supply improvements in Ethiopia: a choice experiment

Improving existing drinking water supply services in developing countries depends crucially on available financial resources. Cost recovery rates of these services are typically low, while demand for more reliable services is high and rapidly growing. Most stated preference-based demand studies in the developing world apply the contingent valuation method and focus on rural areas. This study examines household Willingness to Pay (WTP) for improved water supply services in a choice experiment in an urban area in Ethiopia, a country with the lowest water supply coverage in Sub-Saharan Africa. The design of the choice experiment allows estimation of the value of both drinking water supply reliability and safety. The estimated economic values can be used in policy appraisals of improved supply investment decisions. Despite significant income constraints, households are willing to pay up to 80% extra for improved levels of water supply over and above their current water bill. Women and households living in the poorest part of the city with the lowest service levels value the improvement of water quality most. As expected, also averting behaviour and expenditures play an important role.     

Separation of the redistributive and allocative functions of government: A public choice perspective

The implications of not separating the redistributive and allocative functions of government are examined from a public choice perspective. Many democratic governments lump transfers and public services into a single unified budget. This can distort voter perceptions of the marginal cost of public services relative to the marginal tax price embodied in the taxing institutions employed to generate public revenue. If the median voter's perception of marginal cost is affected, the majority rule outcome with respect to public goods spending will be altered correspondingly.     

Islamic constitutionalism and rule of law: a constitutional economics perspective

This study investigates the relationship between Islamic constitutionalism and rule of law. Al Azhar, one of the most respected Sunni religious institutions in the world, developed a model of an Islamic constitution. This study uses Al-Azhar’s constitution as a model of Islamic constitutionalism and examines its stance in regard to the rule of law. We find the Al-Azhar’s constitution to be incompatible with essential concepts of rule of law. For example, the powers vested in the head of the Islamic state are enormous, making the executive branch of government far superior to the legislative and judicial branches. Women and non-Muslims are explicitly discriminated against throughout the constitution. Moreover, laws stemming from this constitution are not stable since many differences exist among schools of Islamic jurisprudence (fiqh). Consequently, we show that state-of-the-art Islamic constitutionalism lacks essential components needed in any constitution based on rule of law.     

Financial liberalization,private investment and portfolio choice: Financialization of real sectors in emerging markets

Using firm level panel data, we analyze the impacts of rates of return gap between financial and fixed investments under uncertainty on real investment performance in three emerging markets, Argentina, Mexico and Turkey. Employing a portfolio choice model to explain the low fixed investment rates in developing countries during the 1990s, we suggest that rather than investing in irreversible long-term fixed investments, firms may choose to invest in reversible short-term financial investments depending on respective rates of returns and the overall uncertainty in the economy. The empirical results show that increasing rates of return gap and uncertainty have an economically and statistically significant fixed investment reducing effect while the opposite is true with respect to financial investments.
