on the basis of a reproducing kernel space, an iterative algorithm for solving the one-dimensional linear and nonlinear schrödinger equations is presented. the analytical solution is shown in a series form in the reproducing kernel space and the approximate solution is constructed by truncating the series. the convergence of the approximate solution to the analytical solution is also proved. th...

“Moral principle is the foundation of law.” Ronald Dworkin Should gay marriage be legalized? Should abortion be outlawed? Regardless of their answers, people are usually quite confident in them. People have strong intuitions about what behaviors are morally right and wrong, from controversial political and legal issues to everyday interactions with friends, colleagues, and strangers. When the l...

Does the n-issue space in domestic European polities reduce to one, two, or more dimensions? How do these dimensions relate to each other? More broadly, how does dimensionality vary across countries? We attempt to advance our understanding of political contestation in Europe by mapping the dimensionality of the political space across 24 countries using Chapel Hill expert survey (CHES) data. We ...

Recent research has tried to uncover the political space in which the Council of Ministers of the European Union decides. Rather than the left-right conflict or a cleavage between governments with national and supranational attitudes, this article shows that a redistributive dimension, decisively shapes the interactions in this most important legislative body of the European Union. In contrast ...

A well functioning bureaucracy can promote prosperity, as Max Weber maintained. But when bureaucracy gets jammed—a Kafkian situation—it causes stagnation. We propose a dynamic theory of the interaction between legislation and the efficiency of bureaucracy. When bureaucracy is inefficient, the effects of politicians’ legislative acts are hard to assess. Incompetent politicians thus have strong i...

This paper develops a simple model to analyse how a lack of political competition may lead to policies that hinder economic growth. We test the predictions of the model on panel data for the US states. In these data, we find robust evidence that lack of political competition in a state is associated with anti-growth policies: higher taxes, lower capital spending, and a reduced likelihood of usi...

My research fields are development economics and political economy. One strand of my research focuses on the role of property rights institutions — the laws, rules and norms that govern how property is allocated, how property can be transferred, and how property is secured. The second strand focuses on political institutions: the constraints and rules governing policy makers, and the representa...
