Döring T. and Schnellenbach J. (2006) What do we know about geographical knowledge spillovers and regional growth?: a survey of the literature, Regional Studies 40, 375–395. Modern (endogenous) growth theory tells us that knowledge is crucial for the sustained growth of high-income economies. Against this background, the paper provides a survey of theoretical and empirical findings highlighting the question of how geographically limited knowledge diffusion can help to explain clusters of regions with persistently different levels of growth. It discusses this topic in two steps. First, the theoretical concept of knowledge spillovers is outlined by discussing the different types of knowledge, the spatial dimension of knowledge spillovers, and the geographical mechanisms and structural conditions of knowledge diffusion. Second, it analyses the empirical evidence concerning the theoretical propositions.
This paper examines the interplay of horizontal and vertical reci- procity in determining the degree of tax compliance. Horizontal reciprocity is of the type that is frequently observed in public goods games, where reciprocally minded taxpayers may respond to non-contributing, strictly sel sh taxpayers by mimicking their sel sh behaviour. Vertical reciprocity is located in the relationship between the taxpayer and her government. Some recent empirical evidence is suggesting that initial cooperation of taxpayers with the scal authorities is not so much the result of positive reciprocity, but rather of a general tendency to obey authorities. Vertical reciprocity is therefore modeled as the propensity of taxpayers to retaliate against an uncooperative government by means of reducing the level of tax compliance. This allows us to identify feedback mechanisms between horizontal and vertical reciprocity.
In 594 BCE, the Athenian lawgiver Solon, called upon to resolve a deepening social crisis, introduced a new constitution and mandated that in civil conflicts, no citizen is to remain apathetic and must take sides. Because the law seemed to support strife, it presents a puzzle. The paper offers a political economy rationale for Solon’s law against neutrality, modeling social conflict as a rent-seeking competition. We divide society into three groups, a hereditary aristocracy, which monopolized power before the Solonian constitution, a rival wealth-based commercial elite, called the new Solonian elite, and the poor, who are enfranchised only partly. We then identify the conditions under which the third group is better off by allying with one of the other groups, protecting the Solonian constitution. In our framework, Solon’s ban on neutrality is an attempt to change the payoffs from violent redistributions of rents, so that conflict is avoided. Accordingly, the ban should not only impede excessive rent seeking, but also prevent the exclusion of any social group.
The Legacy of Open Thought
(2009)
The paper compares decision-making on the centralisation of public goods provision in the presence of regional externalities under representative and direct democratic institutions. A model with two regions, two public goods and regional spillovers is developed in which uncertainty over the true preferences of candidates makes strategic delegation impossible. Instead, it is shown that the existence of rent extraction by delegates alone suffices to make cooperative centralisation more likely through representative democracy. In the non-cooperative case, the more extensive possibilities for institutional design under representative democracy increase the likelihood of centralisation. Direct democracy may thus be interpreted as a federalism-preserving institution.
In contrast to the contractarian approach to constitutional economics, we follow Voigt (1999) in assuming that constitutional rules are closely connected to informal institutions and that their evolution is a matter of interest group activity and implicit re-interpretation. We add to this the assumption of theoretical uncertainty of individuals regarding the working properties of constitutional rules. Collective learning processes are considered as the third driving force of constitutional evolution, and at the same time as the source of path-dependencies which allow suboptimal constitutions to persist. Finally, it is argued that direct legislation offers more protection than a written fiscal constitution.
