Solving the Winner Determination Problem in a Divisible-Object Auction

In an auction of a divisible object, bidders' demand functions are often assumed to be nonincreasing, meaning that bidders are willing to pay less or the same price for every additional unit. Under this assumption, the optimal allocation that maximizes the auctioneer's revenue can be found using a greedy-based procedure. This article argues that situations may arise where a bidder may need to express her preferences through a nondecreasing demand function; when such a bidder is present in the auction, the greedy-based procedure does not guarantee the optimal allocation. Thus, this article proposes a mixed integer program that finds the optimal allocation in a divisible-object auction at which bidders submit their bids as arbitrary stepwise demand functions. The practical aspect of the mathematical program is presented by means of a simple yet illustrative example in a treasury bond auction setting. The results of the auctioneer's revenue are reported as a function of the number of bidders with nonincreasing and nondecreasing demand functions.     

Including vulnerable groups in financial services: insights from consumer satisfaction

The crisis brought into relief problems within the financial sector which seriously affected consumer trust. This paper provides new evidence on the experiences of two socio-economic groups associated with potential vulnerability – the less educated and the elderly – with financial service markets across Europe. We find that the less educated and the elderly are less satisfied and experience greater difficulties than other consumers as regards complaining, comparing offers, or switching, in the mortgage, and investment product and bank account markets, respectively. This evidence is of use to policy-makers seeking ways of improving financial regulation from a consumer perspective.     

Corporate social responsibility perception in business students as future managers: a multifactorial analysis

This paper examines undergraduate business students' perception of corporate social responsibility (CSR) in cases in which they have not attended any specific course either dealing with CSR or providing training in ethics. A survey was conducted of 535 Spanish business students as future managers. The results show that the stakeholders' perspective deserves a huge attention for those students considering what the keys of business success are. Significant differences in perception were nevertheless identified when a multifactorial analysis was undertaken. Female students are more concerned about CSR issues. The maximization of value for shareholders is less valued by second‐ and third‐year students than by first‐year ones. The findings point to a number of important orientations for the future development of university curriculum.     

Does having women managers lead to increased gender equality practices in corporate social responsibility?

There is increasing interest in determining what impact having women in management positions may have on corporate social responsibility (CSR) initiatives. Various authors suggest that gender equality practices should be factored into the broader framework of CSR. This paper examines how the presence of women on corporate boards, in top and middle management and as heads of CSR departments, influences gender equality practices in the field of CSR. Using information collected from companies that have signed up to Women's Empowerment Principles in Spain, we show that the presence of women in the aforesaid posts has a positive impact on CSR activities with gender equality objectives. We thus supplement the justice, business and moral arguments with further arguments in support of the incorporation of women into not only corporate boards but all management positions. Finally, we provide a view of how gender equality can be included in the broader framework of CSR.     

Formation of monopolies in a bipartite market

We study the formation of monopolies in a simplified economic model where two brands compete in the market, using an agent based model. Each agent represents a company that uses one of the two available brands and interacts with other companies. The brands continually improve their product in order to compete for market share. In the innovation process companies can decide to change to the other brand if the move is beneficial. There is a cost for the company if it decides to switch to the other brand, and another cost if it stays with its current brand but only upgrades to a new enhanced version of the product. Our simulations show that the system always reaches a state when all companies end using a single brand, which is equivalent to a monopoly. We study the time span needed to reach the single brand final state for different parameters of the model.     

The economic consequences of the Spanish Reconquest: the long-term effects of Medieval conquest and colonization

This paper shows that a historical process that ended more than five centuries ago, the Reconquest, is very important to explain Spanish regional economic development down to the present day. An indicator measuring the rate of Reconquest reveals a heavily negative effect on current income differences across the Spanish provinces. A main intervening factor in the impact the Reconquest has had is the concentration of economic and political power in a few hands, excluding large segments of the population from access to economic opportunities when Spain entered the industrialization phase. The timing of the effect is consistent with this argument. A general implication of our analysis is that large frontier expansions may favor a political equilibrium among the colonizing agents that is biased toward the elite, creating the conditions for an inegalitarian society, with negative consequences for long-term economic development.     

Dinámica de la inversión extranjera directa en los estados de México: un análisis de cadenas de Markov espaciales

The aim of this investigation is to analyze the evolution of the spatio-temporal distribution of foreign direct investment (FDI) across Mexican states. The literature that analizes foreign direct invesment in Mexico is numerous and diverse; however, it is argued that the analysis of the spatio-temporal distribution of FDI conditioned to spatial interaction effects in Mexico, is still absence. In this sense, by applying the spatial Markov chain approach as proposed by Rey (2001), we found a divergence process in the FDI inflows among mexican states that seems to get stronger over time. In particular, during the period from 2006 to 2013, the process of divergence towards higher-FDI-inflows quantiles occurs among states spatially associated with neighbors in lower-FDI-quantiles.
