Designing democracy : ideas for better rules by Hans Gersbach( Book )

21 editions published between 2004 and 2010 in English and German and held by 197 WorldCat member libraries worldwide

This book presents a number of ideas for drawing up new rules to improve the functioning of democracies. The first part examines ways of combining incentive contracts with democratic elections. The second part presents new rules for decision-making, agendas and agenda settings

Financial intermediation and the creation of macroeconomic risks by Hans Gersbach( Book )

17 editions published between 1998 and 2008 in English and held by 50 WorldCat member libraries worldwide

We examine financial intermediation when banks can offer deposit or loan contracts contingent on macroeconomic shocks. We show that the risk allocation is efficient if there is no workout of banking crises. In this case, banks will shift part of the risk to depositors. In contrast, under a workout of banking crises, depositors receive non-contingent contracts with high interest rates while enterpreneurs obtain loan contracts that demand a high repayment in good times and little in bad times. As a result, the present generation overinvests and banks create large macroeconomic risks for future generations, even if the underlying risk is small or zero. This provides a new justification for capital requirements
Imperfect competition in product markets and labor markets, general equilibrium and unemployment by Hans Gersbach( Book )

19 editions published between 1999 and 2005 in English and held by 49 WorldCat member libraries worldwide

We examine wage-bargaining in a two-sector economy when employers and labor unions in each sector are not always aware of all general equilibrium feedback effects. We show analytically that if agents only consider labor demand effects, low real wages and low unemployment result. With an intermediate view, i.e. when partial equilibrium effects within a sector are taken into account, high real wages and unemployment result. If all general equilibrium effects are considered at once, low real wages and low unemployment again result. The assumption that unions and employers' federations are not able to incorporate all feedback effects from other sectors may explain the persistence of high unemployment in Europe
Democratic mechanisms : double majority rules and flexible agenda costs by Hans Gersbach( Book )

15 editions published between 2000 and 2014 in English and held by 44 WorldCat member libraries worldwide

We introduce democratic mechanisms where individual utilities are not observable by other people at the legislative stage. We show that the combination of three rules can yield e±cient provision of public projects: first, flexible and double majority rules where the size of the majority depends on the proposal and taxed and non-taxed individuals need to support the proposal; second, flexible agenda costs where the agenda-setter has to pay a certain amount of money if his proposal does not generate enough supporting votes; third, a ban on subsidies. We also illustrate that higher dimensional uncertainty about project parameters can make it easier to achieve first-best allocations and that universal equal treatment with regard to taxation is undesirable
Competition of politicians for incentive contracts and elections by Hans Gersbach( Book )

15 editions published between 2000 and 2012 in English and Undetermined and held by 43 WorldCat member libraries worldwide

In this paper we examine the impact of tax contracts, a novel instrument, on elections, policies, and welfare. We consider a political game in which three parties compete to form the government and voters may behave strategically. Parties have policy preferences about the level of public-good provision and benefit from perks when in office. A government raises taxes for both purposes. We show that tax contracts yield moderate policies and lead to lower perks by avoiding the formation of grand coalitions in order to win government. Moreover, in polarized societies they unambiguously improve the welfare of the median voter
Economic Growth, Education, And AIDS In Kenya A Long-Run Analysis by Clive Bell( )

3 editions published between 2006 and 2012 in English and Undetermined and held by 35 WorldCat member libraries worldwide

The AIDS epidemic threatens Kenya with a long wave of premature adult mortality, and thus with an enduring setback to the formation of human capital and economic growth. To investigate this possibility, the authors develop a model with three overlapping generations, calibrate it to the demographic and economic series from 1950 until 1990, and then perform simulations for the period ending in 2050 under alternative assumptions about demographic developments, including the counterfactual in which there is no epidemic. Although AIDS does not bring about a catastrophic economic collapse, it does cause large economic costs-and many deaths. Programs that subsidize post-primary education and combat the epidemic are both socially profitable-the latter strikingly so, due to its indirect effects on the expected returns to education-and a combination of the two interventions profits from a modest long-run synergy effect
Competitive markets, collective decisions and group formation by Hans Gersbach( Book )

10 editions published between 1998 and 2003 in English and held by 34 WorldCat member libraries worldwide

We consider a general equilibrium model where groups operating in a competitive market environment can have several members and make efficient collective consumption decisions. Individuals have the option to leave the group and make it on their own or join another group. We study the effect of these outside options on group formation, group stability, equilibrium existence, and equilibrium efficiency
Reelection threshold contracts in politics by Hans Gersbach( Book )

13 editions published between 2001 and 2013 in English and held by 34 WorldCat member libraries worldwide

When politicians are provided with insufficient incentives by the democratic election mechanism, we show that social welfare can be improved by threshold contracts. A threshold incentive contract stipulates a performance level which a politican must reach in order to have the right to stand for reelection. Read my lips would turn into read my contracts. Reelection thresholds can be offered by politicians during campaigns and do not impair the liberal principle of free and anonymous elections in democracies

Debt contracts, collapse and regulation as competition phenomena by Hans Gersbach( Book )

13 editions published between 1997 and 1998 in English and held by 33 WorldCat member libraries worldwide

This paper studies a credit market with adverse selection and moral hazard where sufficient sorting is impossible.The crucial novel feature is the competition between lenders in their choice of contracts offered. Qualities of investment projects are not observable by banks and investment decisions of entrepreneurs are not contractible, but output conditional on investment is. We explain the empirically observed prevalence of debt contracts as an equilibrium phenomenon with competing lenders. Equilibrium contracts must be immune against raisin{picking by competitors. Non{debt contracts allow competitors to offer sweet deals to particularly good debtors, who will self{select to choose such a deal, while bad debtors distribute themselves across all offered contracts. Competition of banks introduces three possibilities for a breakdown of credit markets that do not occur when a bank has a monopoly. First, average returns decrease since banks compete for good lenders which may make the lending altogether unprofitable. Second, banks can have an incentive to offer a debt contract and additional equity contracts to intermediate debtors. This combination, however, is in turn dominated by a simple debt contract that is only attractive for very good entrepreneurs. As a result no equilibrium in pure strategies exists. Existence can be restored, if the permissible types of contracts are limited by regulation resembling the separation of investment and commercial banking in the U.S.Third, allowing for random delivery on credit contracts leads to a break-down since all banks want to avoid the contract with the highest chance of delivery: that contract attracts all bad entrepreneurs
Emission taxes and the design of refunding schemes by Hans Gersbach( Book )

8 editions published in 2000 in English and held by 33 WorldCat member libraries worldwide

We examine how emission taxes should be refunded to firms in order to create optimal incentives to invest in cleaner technologies. Since refunds cannot be made dependent on investments, an alternative way is to give back taxes to firms according to market shares. We show that universally applicable refunding schemes must be linear in market shares. Moreover, a socially optimal tax/tax refunding scheme exists if pollution is proportional to output and firms compete à la Cournot. If short-term abatement technologies exist, tax/tax refunding schemes can still provide second-best allocations. If firms are price takers, however, refunding taxes according to market shares is harmful. Since imperfect competition is a prominent phenomenon in many polluting industries, the design of socially optimal refunding schemes is an essential part of environmental regulation
The dynamics of deposit insurance and the consumption trap by Hans Gersbach( Book )

11 editions published in 2001 in English and held by 33 WorldCat member libraries worldwide

We investigate a banking system subject to repeated macroeconomic shocks and show that without deposit rate control, the banking system collapses with certainty. Any initial level of reserves will delay the collapse but not avoid it. Even without a banking collapse, the economy still converges to a consumption trap with positive probability. Savings are maximal in the consumption trap, but are used entirely to pay back obligations of banks. No long-term investments can be financed and GDP is minimal. We discuss stronger intervention rules that avoid both a collapse and the consumption trap, confirming that capital requirements are an early indicator signaling when intervention may become necessary. Our analysis provides an explanation why economies which experience a banking crisis may endure long-lasting economic downturns
Flexible majority rules by Ulrich Erlenmaier( Book )

9 editions published between 1999 and 2001 in English and German and held by 31 WorldCat member libraries worldwide

In this paper we introduce flexible majority decision rules where the size of the majority depends on the proposal made by the agenda setter. Flexible majority rules can mitigate the disadvantages of democracies in the provision of public projekts. In many cases, the combination of the priciples taxation constraint to majority winners, a ban of subsidies, costly agenda setting and flexible majority rules constitute a socially optimal democratic constitution. Flexible majority rules might also be a useful decision-making procedure in other circumstances
The long-run economic costs of AIDS : theory and an application to South Africa by Clive Bell( Book )

9 editions published in 2003 in English and held by 31 WorldCat member libraries worldwide

Most existing estimates of the macroeconomic costs of AIDS, as measured by the reduction in the growth rate of gross domestic product, are modest. For Africa--the continent where the epidemic has hit the hardest--they range between 0.3 and 1.5 percent annually. The reason is that these estimates are based on an underlying assumption that the main effect of increased mortality is to relieve pressure on existing land and physical capital so that output per head is little affected. Bell, Devarajan, and Gersbach argue that this emphasis is misplaced and that, with a more plausible view of how the economy functions over the long run, the economic costs of AIDS are almost certain to be much higher. Not only does AIDS destroy existing human capital, but by killing mostly young adults, it also weakens the mechanism through which knowledge and abilities are transmitted from one generation to the next. The children of AIDS victims will be left without one or both parents to love, raise, and educate them. The model yields the following results. In the absence of AIDS, the counterfactual benchmark, there is modest growth, with universal and complete education attained within three generations. But if nothing is done to combat the epidemic, a complete economic collapse will occur within three generations. With optimal spending on combating the disease, and if there is pooling, growth is maintained, albeit at a somewhat slower rate than in the benchmark case in the absence of AIDS. If pooling breaks down and is replaced by nuclear families, growth will be slower still. Indeed, if school attendance subsidies are not possible, growth will be distinctly sluggish. In all three cases, the additional fiscal burden of intervention will be large, which reinforces the gravity of the findings. This paper--a product of the Office of the Vice President, Human Development Network--is part of a larger effort in the network to evaluate the economic consequences of HIV/AIDS

Economic growth, education, and AIDS in Kenya : a long-run analysis by Clive Bell( Book )

Growth and epidemic diseases by Clive Bell( Book )

14 editions published between 2004 and 2006 in English and German and held by 27 WorldCat member libraries worldwide

This paper studies the formation of human capital and its transmission across generations when premature adult mortality is a salient feature of the demographic landscape, either permanently or in the form of a long-period wave that follows the outbreak of an epidemic. We establish several threshold properties of the model, for such a shock can severely retard economic growth, even to the point of leading to an economic collapse. Premature adult mortality may exacerbate inequality under nuclear family arrangements. Pooling mortality risks with equal treatment of all children may fend off, or even induce, a collapse, depending on the initial conditions and the size and duration of the shock. Awareness campaigns may also trigger a collapse by introducing undesirable expectational feedbacks
Self-financing environmental mechanisms by Jörg Breitscheidel( Book )

7 editions published between 2002 and 2005 in English and held by 23 WorldCat member libraries worldwide

We explore the design of self-financing tax/subsidy mechanisms to solve hold-up problems in environmental regulation. Under Cournot competition, announcing the subsidy rate seems to be preferable to announcing the tax rate. Moreover, for constant marginal damage the hold-up problem can always be solved by setting subsidies. Under Bertrand competition, only announcing the tax rate can induce at least one firm to invest. We suggest that feebate systems in the automotive sector should be designed as self-financing tax/subsidy mechanisms
Cake division by majority decision by Hans Gersbach( Book )

6 editions published in 2006 in English and German and held by 14 WorldCat member libraries worldwide

We consider a collective choice process where three players make proposals sequentially on how to divide a given quantity of resources. Afterwards, one of the proposals is chosen by majority decision. If no proposal obtains a majority, a proposal is drawn by lot. We establish the existence of the set of subgame perfect equilibria, using a suitable refinement concept. In any equilibrium, the first agent offers the whole cake to the second proposal-maker, who in turn offers the whole cake back to the first agent. The third agent is then indifferent about dividing the cake between himself and the first or the second agent
