On absolute auctions and secret reserve prices

From a theory viewpoint, the use of auctions with zero public reserve prices, also called absolute auctions, or of auctions with secret reserve prices, is somewhat puzzling despite being common. By allowing that buyers differ in their processing of past data regarding how the participation rate varies with the auction format and how reserve prices are distributed when secret, we show in a competitive environment that these auction formats may endogenously emerge. We also analyze how buyers with various sophistications and sellers with various costs sort into the different formats, thereby offering a range of testable predictions. Alternative approaches are reviewed.     

Wages,Productivity and Labour's Declining Income Share in Post‐Apartheid South Africa

The Marikana incident in 2012, as well as the protracted strikes by platinum miners, metal and postal workers in 2014 suggest that not all is well in the South African labour market. Even though those in employment are better off than the unemployed poor, macroeconomic data indicate that labour's share in gross value added has declined significantly during the first two decades following the first democratic election in 1994. A falling share of labour in income also means, by definition, that average labour productivity growth outstrips real wages growth. Data for South Africa suggest that productivity has indeed increased faster than wages in South Africa. This article argues that financialisation and more aggressive returns‐oriented investment strategies applied by for instance large investment institutions translated into higher required rates of return on capital, which in turn caused an increased implementation of capital‐augmenting labour‐saving technology that reduces labour's share in income.     

Export Restrictions and Smooth Transition Cointegration: Export Quotas for Wheat in Ukraine

We extend previous modelling approaches to identify domestic price effects of export controls. We allow for smooth transition between free‐trade price transmission regimes and those under export restricting regimes, using a smooth transition cointegration (STC) approach, rather than the more common assumption that regime changes are abrupt. Our approach has the advantage that the switch in the price transmission regime may be induced not only by an actual but also by an expected policy change. Results confirm the gradual nature of the transition between the regimes, which reflect trader heterogeneity and wheat storage decisions. We find that the STC approach outperforms alternative model approaches in terms of both regime classification and goodness of fit, when explaining Ukrainian domestic wheat prices under export controls. In particular, application of the Markov‐switching error correction model (MSECM) to the same data generates results which do not reflect any identifiable economic reality (in contrast to Götz et al., 2013 ).     

Disutility of pollution and endogenous growth

Endogenous growth is generally built on a positive externality hypothesis which is the opposite of a negative externality caused by pollution. We study a linear technology with simple assumption: an aggregate capital stock which represents a learning by doing effect and a pollution flow proportional to production. In this framework, we analyse the precise effects on growth of the disutility of pollution and its interaction with the utility of consumption in an economy without abatement technology. The decentralized equilibrium always leads to unlimited growth, but optimal growth is often limited (the negative effect of pollution dominating the positive effect of learning by doing). In this case, the optimal policy which leads the decentralized economy to follow the optimal growth path is to tax capital; in contrast with the optimal subsidy policy in an economy without pollution. When an abatement technology is introduced, the optimal solution can lead the economy to unlimited growth, whatever the form of the utility function.     

Trade,environment, and income inequality: An optimal taxation approach

In a small open economy, how should a government pursuing both environmental and redistributive objectives design domestic taxes when redistribution is costly? And how does trade liberalization affect the economy's levels of pollution and inequalities, when taxes are optimally and endogenously adjusted? Using a general equilibrium model under asymmetric information with two goods, two factors (skilled and unskilled labor), and pollution, this paper characterizes the optimal mixed tax system (nonlinear income tax and linear commodity and production taxes/subsidies) with both production and consumption externalities. While optimal income taxes are not directly affected by environmental externalities, conditions are derived under which under‐ or over‐internalization of social marginal damage is optimal for redistributive considerations. Assuming that redistribution operates in favor of the unskilled workers and that the dirty sector is intensive in unskilled labor, simulations suggest that trade liberalization involves a clear trade‐off between the reduction of inequalities and the control of pollution when the source of externality is only production; this is not necessarily true with a consumption externality. Finally, an increase in the willingness to redistribute income toward the unskilled results paradoxically in less pollution and more income inequalities.     

Does God practice a random walk? The 'financial physics' of a nineteenth-century forerunner,Jules Regnault

We analyse the work of a neglected French economist, Jules Regnault, whose Calcul des Chances et Philosophie de la Bourse (1863) laid the basis of modern stochastic models of price behaviour and contains an anticipation of econometrics. At a time when short-term speculation was denounced as immoral, he approached this question ‘scientifically’ and constructed two models. The first one was relative to short-term speculation and took the shape of a random walk - a model used by Bachelier (1900). The second one deals with long-term speculation and aims at evaluating the mean value of the French 3 per cent bond.     

Luenberger and Malmquist Productivity Indices: Theoretical Comparisons and Empirical Illustration

This contribution establishes, from a theoretical viewpoint, the relations between the Malmquist productivity indices, that measure in either input or output orientations, and the Luenberger productivity indices, that can simultaneously contract inputs and expand outputs, but that can also measure in either input or output orientations. The main result is that a Malmquist productivity index overestimates productivity changes, since it provides productivity measures that are nearly twice those given by the Luenberger productivity index looking for simultaneous contractions of inputs and expansions of outputs. This relationship is empirically illustrated using data from 20 OECD countries over the 1974–97 period.     

Flexible labour markets and individualized employment: the beginnings of a new Japanese HRM system?

In an earlier study we reported that human resource management (HRM) in Japan was best characterized by continuity with some changes to assessment and pay practices. It is now over five years since we mapped out the changes taking place in Japanese HRM. This contribution reviews some of the changes over this period and considers the future directions of HRM. The essay commences with a discussion of the important contextual factors and issues underpinning HRM including employer proposals for reform. The next section then explores changes taking place in employment, remuneration and evaluation. This is supplemented by a more general assessment of the key changes occurring in Japanese HRM. The essay concludes with a discussion on why such changes are occurring, whether the changes constitute a convergence towards the Western model and the implications for HRM and theory development.     

A new entrepreneurial drive in large and small manufacturing firms in Japan

Japan's per capita GDP growth has been decelerating for at least three decades, despite groping towards better ways of accommodating individualistic Smithian market forces. Japan has made great progress in opening markets and fostering profit seeking, yet it has not reaped the benefits anticipated so far. Facing the most severe economic downturn of the post-war period, it is now rethinking the fundaments of its economic and management system. The necessity of developing competitive advantages in new industries has been identified but a crucial question is how they will affect the way industry has organized itself to maximize quality, efficiency and flexibility. It is said that an entrepreneurial culture was not needed during the post-war period in Japan because a group-based industrial organization could generate about the same dynamism and outcome. Nevertheless, this time, a venture-type business culture may be a key factor in the renewal of the Japanese economy to put it back on a sustainable growth path. The objective of the article is to make a critical assessment of the trends in entrepreneurship in Japan, using secondary data. They are complemented by partial results of two surveys made by the author, the first one in 1997 in ten electronic companies on intrapreneurship schemes, and the second one in 1998 in 40 small companies in the Hiroshima prefecture, centred on human resource management. To these are added information obtained through interviews in the small business agency, MITI, and a number of universities on business-university research collaboration schemes.
