Lobbying For Tariff Policies*

This paper fully specifies the political and economic markets in which trade policies are formulated and lobbying efforts are determined. In the political market, the winner of a two-candidate race chooses policies, and both candidates have incomplete information about the nonpolicy biases of voters. Voting is probabilistic and lobbying consists of informing candidates of the lobby members' nonpolicy voting biases. Economic markets are described by a Heckscher-Ohlin model. the determinants of lobbying expenditures are developed from these microfoundations instead of being introduced in an ad hoc manner.     

Structural Change for Economic Growth

As soon as the post-war era of rapid economic growth had come to an end in the early 1970s, the intellectural fashion being to swing towards a renewed appreciation of economic growth and the 'classical' factors of growth saving hard work, enterprise, innovation and a legal framework which secures the property rights to the rewards of material progress and facilitates flexible adjustment by a competitives system. Professor Wolfgang Kasper of the University of New South Wales in Australia argues that the major challenge for societies in West and East, North and South alike is now to make the supply side of the economy more elastic and responsive to new opparatunities and circumstances.     

Development policy in crisis

The present crisis symptoms evident in most developing economies are particularly pronounced in black Africa. Although this is largely due to factors beyond the control of the countries concerned, inappropriate development strategies have aggravated their effects. In order to mobilize the black African countries' own potential for development, a reorientation of both their internal policies and their cooperation with industrialised countries is called for.

A Benchmark Approach to Portfolio Optimization under Partial Information

This paper proposes a filtering methodology for portfolio optimization when some factors of the underlying model are only partially observed. The level of information is given by the observed quantities that are here supposed to be the primary securities and empirical log-price covariations. For a given level of information we determine the growth optimal portfolio, identify locally optimal portfolios that are located on a corresponding Markowitz efficient frontier and present an approach for expected utility maximization. We also present an expected utility indifference pricing approach under partial information for the pricing of nonreplicable contracts. This results in a real world pricing formula under partial information that turns out to be independent of the subjective utility of the investor and for which an equivalent risk neutral probability measure need not exist.      

Risk aversion vs. individualism: what drives risk taking in household finance?

Despite a considerable premium on equity with respect to risk-free assets, many households do not own stocks. We ask why the prevalence of stockholding is so limited. We focus on individuals’ attitudes toward risk and identify relevant factors that affect the willingness to take financial risks. Our empirical evidence contradicts standard portfolio theory, as it does not indicate a significant relationship between risk aversion and financial risk taking. However, our analysis supports the behavioral view that psychological factors rooted in national culture affect portfolio choice. Individualism, which is linked to overconfidence and overoptimism, has a significantly positive effect on financial risk taking. In microdata from Germany and Singapore, as well as in cross-country data, we find evidence consistent with low levels of individualism being an important factor in explaining the limited participation puzzle.     

Wang Anshi and the origins of modern public management in Song Dynasty China

Wang Anshi (1021–1086) is well known as one of the greatest statesmen of classical China, but it is rarely recognized that his 1058 ‘Wan Yan Shu’ is one of the first texts of public management in the modern sense. This is because Wang addressed still current concerns of a civil service—selection, training, motivation, remuneration—often presenting solutions that are completely in line with today's perspectives. Wang's work is particularly relevant now given the current global state of public management—post-NPM but with no clear new paradigm having emerged.
