A contest model of liberalizing government procurements

This paper models liberalization of government procurements as admitting entry of foreign firms in a contest among potential rent seekers. It contributes to the literature on how institutions influence socially desirable outcomes. Liberalizing procurements reduces wasteful domestic lobbying but also increases the likelihood that a foreign firm will capture the rent. A main result is that the domestic welfare change is not monotonic in the foreign firms' abilities. Furthermore, we show that domestic liberalization policies can be inefficient from the global point of view because foreign lobbying costs can outweight productive efficiency.     

Corruption and re-election: how much can politicians steal before getting punished?

Can corruption be used to improve re-election chances of politicians in office? What is the optimal level of corruption for doing so? In this paper I use suspicious patterns of public procurement allocations in local government as a proxy measurement of corruption, based on combining quantitative and qualitative evidence on corrupt practices in local government. I then tie suspicious procurements to re-election probabilities of mayors in Croatian cities and municipalities from 2009 to 2017, and find that due to a rent-extracting relationship formed between firms and political elites, local politicians can engage in potential corruption and still win elections. There is an optimal level of suspicious procurements for which politicians maximize their re-election chances. When a mayor surpasses the cut-off level of around 20% of suspiciously allocated funds from public procurement his or her probability of re-election starts to decline, while he or she loses office for at least one half of all procurements allocated suspiciously. In order to address potential endogeneity issues I apply a fuzzy regression discontinuity design based on population thresholds that determine the size of the local council, where the intensity of the treatment (potential corruption) increases with increasing council size. The results overall confirm the hypothesized nonlinear relationship between corruption and re-election.

Corruption in delegated public procurement auctions

In this paper we theoretically analyse effects of corruption in public procurements within a scoring-auction framework. A corrupt politician, who acts on behalf of the public sector, receives a kickback from the winning bidder. The politician selects the scoring rule. The paper shows that such corruption always leads to lower quality and lower price. Given a level of corruption, a higher bargaining power of the politician in extracting bribes does not affect the quality but leads to higher price.     

Network Effects on Trade in Intermediate Goods: Evidence from the Automobile Industry

Growing production fragmentation makes the analysis of network effects on trade in intermediate goods more important than ever. The present study measures network effects on auto parts exports from 6 major auto producing countries using a panel data set covering 49 destinations and 31 products from 2002 to 2008. In contrast to prior research, the present study finds that in the case of Japanese automakers, overseas production by subsidiary plants is less important in determining auto parts exports from Japan than it is for the other major auto producing countries. Such uniqueness could be led by the higher reliance on domestic procurements of overseas subsidiaries of Japanese automakers as a result of the transfer of the vertical networks between automakers and parts suppliers formed in Japan.     

Competition in the economic crisis: Analysis of procurement auctions

We study the effects of the recent economic crisis on firms׳ bidding behavior and markups in sealed bid auctions. Using data from Austrian construction procurements, we estimate bidders׳ construction costs within a private value auction model. We find that markups of all bids submitted decrease by 1.5 percentage points in the recent economic crisis, markups of winning bids decrease by 3.3 percentage points. We also find that without the government stimulus package this decrease would have been larger. These two pieces of evidence point to pro-cyclical markups.     

External military threat and the response of the member states of the Gulf Co-operation Council (GCC)

The study shows that procurements of traditional arms by two countries have the possibility of moving together over time. This is demonstrated with reference to Iran and the member states of the Gulf Co-operation Council (GCC) for the period 1961- 1996. Acquiring arms by the member states of the GCC is shown to be only a response to the perception of their leaders to the external threat posed by Iran throughout the varying regimes that have ruled Teheran. In the light of the recent emergence of macroeconomic problems such as unemployment in the economies of the GCC coupled with the ineffectiveness of the financially exhausting build-up of arms as a military deterrent policy, one important implication of the study is that the priority of the GCC leaders will have to turn to a more effective deterrent policy such as acquiring nuclear technology rather than engaging in a costly and unsuccessful Arab military alliance as experienced in the 1970s.     

Barriers to technological adoption in Spain and Portugal

Since 1945, both Spain and Portugal have experienced significant market transformations. These countries were both led by dictators for many years until the mid 1970s when each moved toward more democratic governments and more open markets. As a result, each experienced significant changes in output with Spain’s becoming a model for proper market based transformations. Although Portugal’s transformation has been less impressive it experienced improvements too. This paper uses a Parente and Prescott (J Polit Econ 102(2), 298–321, 1994; 2000) type model to investigate the recent transformations in each of these countries and quantify the extent to which barriers to technological adoption may have played for these two development experiences. Our results indicate that from 1945 to 2003 these barriers have fallen considerably but remain high, and are somewhat higher in Portugal than in Spain.

Visioning the regional future: Globalization and regional transformation of Rabat/Casablanca

The mainstream literature on globalization and regional transformation emphasizes two major perspectives. The first perspective combines global city theory with macro theories of transformations with a normative bias often leading to deterministic conceptualisations of globalization links to regional transformation. The other perspective emphasizes economy as the most important if not the only pushing factor for regional transformations with little attention to all transformations involving soft and informal structures The latter may be vital for such transformation. This paper takes a completely new approach namely to analyse local stakeholders' visions of regional transformation of the Rabat/Casablanca region in face the challenges that globalization poses.     

An Investigation of the Effects of Data Transformation on Nonlinearity

This paper investigates the effects of data transformation on nonlinearity by means of a simulation analysis based on empirical threshold models for the unemployment rate. Unemployment rate series are particularly suitable because they exhibit a number of interesting features: business cycle asymmetries, persistence, long memory and seasonality. The main finding is that evidence of nonlinearity is not independent of the form in which data are analysed and that most data transformations result in a loss of nonlinearity. This is particularly the case for seasonal adjustment transformations, which remove not only seasonality but also nonlinear features, as shown for the commonly applied Census X12 method.     

Scale equivariance and the Box-Cox transformation

The Box-Cox family of transformations has two useful features: first, it includes linear and logarithmic transformations as special cases; and, second, it possesses strong scale equivariance properties, including the property that the transformation parameter is unaffected by the rescaling. Its main disadvantage is that both the domain and the range of the transformation are, in general, bounded. We show that, for a certain class of models, if a model demonstrates these scale equivariance properties for the dependent variable then the transformation on the dependent variable must be a variant of the Box-Cox transformation.     

Goodwin’s structural economic dynamics: Modelling Schumpeterian and Keynesian insights

In this paper we pursue the work started jointly with R. Goodwin in the 1990s. Goodwin’s later work went very much in the direction of modelling Schumpeter’s insights into structural and technological transformations in the context of disaggregated models while allowing for non-full employment outcomes and macroeconomic cyclical patterns to develop alongside these transformations. In a series of papers we have followed up this work for closed and open economies, drawing out in particular the implications of structural transformations for macro-distributional dynamics and effective demand problems. This has been analysed for advanced and catching-up economies and their interdependencies on the global stage. We shall review our modelling efforts in this respect and trace these back to Goodwin’s life-long preoccupation with synthesising disaggregated (linear) modelling with macro-dynamic analysis.     

The transformations of utility theory: a behavioral perspective

The aim of this paper is threefold. First, it reappraises the major transformations which the utilitarian approach to human behavior has undergone in economics in search for a representation by utility functions and later by preference orders. Second, in the light of today’s behavioral and human sciences, an attempt is made to restore some elements of early utilitarianism that were abandoned in these transformations. Third, in line with the interest of the early utilitarians in both explaining behavior and elaborating on its moral assessment, the present paper also discusses some normative implications of the suggested restoration of utilitarian theory.     

A family of ordinal solutions to bargaining problems with many players

A solution to bargaining problems is ordinal when it is covariant with respect to order-preserving transformations of utility. Shapley has constructed an ordinal, symmetric, efficient solution to three-player problems. Here, we extend Shapley's solution in two directions. First, we extend it to more than three players. Second, we show that this extension lends itself to the construction of a continuum of ordinal, symmetric, efficient solutions. The construction makes use of ordinal path-valued solutions that were suggested and studied by O'Neil et al. [Games Econ. Behav. 48 (2004) 139–153].     

Heteroscedasticity and the use of Box–Cox transformations

Direct and inverse power Box–Cox transformations are used to characterize the form of heteroscedasticity in models where the variables themselves are subjected to direct Box–Cox transformations. Resulting formulations are extended to take serial correlation simultaneousy into account.

Critical Political Economy and Material Transformation

The starting point for this paper is that critical political economy needs to take up the challenge that originates in Marx's seminal contributions of conceptualising the economy as both processes of value creation and processes of material transformations. This is because, inter alia, the successful production of commodities requires knowledge of their constituent materials and their potential transformations and the ways in which these can be managed through the production process to allow the creation of surplus value and profits. Using the steel and automobile industries as an example, I show how a wide range of materials can be produced with a variety of desirable properties through careful control of the production process. Sophisticated management of the production process depends upon the knowledge of the properties of the materials and of the ways in which these can be combined and transformed to give types of steels with particular desired combination of properties. Capitalist interests have increasingly shaped the processes of R&D through which knowledge about the materials, their properties and their transformations has been developed and deployed to produce profits via producing steel and – inter alia – automobiles.     

Ethically robust comparisons of bidimensional distributions with an ordinal attribute

We provide foundations for robust normative evaluation of distributions of two attributes, one of which is cardinally measurable and transferable between individuals and the other is ordinal and non-transferable. The result that we establish takes the form of an analogue to the standard Hardy–Littlewood–Pólya theorem for distributions of one cardinal attribute. More specifically, we identify the transformations of the distributions which guarantee that social welfare increases according to utilitarian unanimity provided that the utility function is concave in the cardinal attribute and that its marginal utility with respect to the same attribute is non-increasing in the ordinal attribute. We establish that this unanimity ranking of the distributions is equivalent to the ordered poverty gap quasi-ordering introduced by Bourguignon [12]. Finally, we show that, if one distribution dominates another according to the ordered poverty gap criterion, then the former can be derived from the latter by means of an appropriate and finite sequence of such transformations.     

The shift from theory to innovation: the evolution of Brazilian research frontiers 2005–2011

Proliferation of emerging economies as significant sources of competitive knowledge is a key feature of globalisation, often driven by government policies fostering domestic research-based innovation capabilities. To cast light on this common emerging economy effort to move from catch-up towards the global innovation frontier, we analyse the evolution of the focus of Brazilian research frontiers 2005–2011 with bibliometric methods. Our results demonstrate a gradual and moderate shift from theoretical scientific knowledge to more innovation-centred knowledge in the most influential Brazilian research, indicating the increased prominence and quality of innovation focused efforts in country's knowledge system. Thus, the recent expansion of Brazil's innovation system is accompanied by qualitative transformations of the research system, in part driven by nationally emerging research fields and technologies. Conceptually, we consider the overall importance of scientific research for developing and emerging economy innovation system build-up.
