Water pricing policies,public decision making and farmers' response: implications for water policy

The problems caused by water scarcity demand important changes in the criteria and objectives of water policies. The agricultural sector in Spain consumes up to 80% of all available hydric resources and the need to increase the efficiency of current uses of water in the agricultural sector is at the core of the country's national water policy. One alternative would be to resort to water pricing policies with the aim of providing incentives to save water consumption although it would inflict a certain degree of income losses to the farmers and raise the revenue collected by the water authorities. The objective of this research is to analyze the effect caused by the application of different water pricing policies on water demand, farmers' income and the revenue collected by the government agency. To undertake this analysis a dynamic mathematical programming model has been built that simulates farmers' behavior and their response to different water pricing scenarios. Empirical application of the model has been carried out in several irrigation districts in Spain covering varied farm regions and river basins. Results show that the effects of alternative pricing policies for irrigation water are strongly dependent on regional, structural and institutional conditions and that changing policies produce distinct consequences within the same region and water district. Thus, equivalent water charges would create widespread effects on water savings, farm income and collected government revenue across regions and districts.     

Competition in wholesale markets: Do MNOs compete to host MVNOs?

This paper extends previous research examining wholesale market shares of mobile network operators (MNOs). This study demonstrates that wholesale market concentration has decreased over time because of the increase of competition of MNOs for hosting mobile virtual network operators (MVNOs). However, differences in wholesale market shares between MNOs have not disappeared. We propose that those operators that are late entrants in a market and belong to an international group with a proactive attitude towards hosting virtual operators positively influences wholesale market shares of MNOs. The empirical analysis is based on a panel data from 2000 to 2010 corresponding to MNOs and virtual operators in five European countries with high development of the virtual mobile industry. By closely examining KPN we show how being an international mobile group specialising in the wholesale market across Europe has enabled it to exploit complementarities that exist between traditional and virtual businesses.     

From feudal colonization to agrarian capitalism in Mallorca: Peasant endurance under the rise and fall of large estates (1229–1900)

The colonization of Mallorca gave rise to a late‐feudal agrarian society that evolved towards capitalism based on large estates owned by noblemen who hired large numbers of wage labourers from among smallholders living in agro‐towns, the dispossessed remnants of a formerly wealthier peasantry. These well‐off peasants originated from when the colonization frontier was open in the 13th and 14th centuries, but had been defeated when three peasant–plebeian revolts were crushed. Afterwards, Mallorca followed a latifundist transition towards agrarian capitalism similar to southern Italy or Spain, in sharp contrast with the middle‐peasant paths seen in Catalonia or Valencia. The land rent rose, while agricultural wages fell from 1659 to 1800. Peasant families could not survive, and had to supplement wages with the products of their own plots. This set a socio‐agroecological limit to growth in this agrarian class structure. The agrarian crisis at the end of the 19th century bankrupted the Mallorcan nobility. Bankers bought much of the land and sold it on as small allotments. This expanded the intensive cropping formerly limited to agro‐town belts, giving rise to a new “peasantization”. Despite their subordination, Mallorcan peasants had survived and created complex agroecological landscapes endowed with a rich biocultural heritage.     

Optimisation of water procurement decisions in an irrigation district: the role of option contracts

Water supply instability is one of the main risks faced by irrigation districts and farmers. Water procurement decision optimisation is essential in order to increase supply reliability and reduce costs. Water markets, such as spot purchases or water supply option contracts, can make this decision process more flexible. We analyse the potential interest in an option contract for an irrigation district that has access to several water sources. We apply a stochastic recursive mathematical programming model to simulate the water procurement decisions of an irrigation district's board operating in a context of water supply uncertainty in south‐eastern Spain. We analyse what role different option contracts could play in securing its water supply. Results suggest that the irrigation district would be willing to accept the proposed option contract in most cases subject to realistic values of the option contract financial terms. Of nine different water sources, desalination and the option contract are the main substitutes, where the use of either depends on the contract parameters. The contract premium and optioned volume are the variables that have a greater impact on the irrigation district's decisions.     

Nonlinear Purchasing Power Parity under the Gold Standard

Hegwood and Papell (2002) conclude on the basis of analysis in a linear framework that long-run purchasing power parity (PPP) does not hold for 16 real exchange rate series, which were analyzed in Diebold. I lusted, and Rush (1991) for the period 1792-1913 under the Gold Standard. Rather, PPP deviations are mean-reverting to a changing equilibrium—a quasi PPP (QPPP) theory. We analyze the real exchange rate adjustment mechanism for their data set assuming a nonlinear adjustment process allowing for both a constant and a mean shifting equilibrium. Our results confirm that real exchange rates at that time were stationary, symmetric, nonlinear processes that revert to a nonconstant equilibrium rate. Speeds of adjustment were much quicker when breaks were allowed.     

Protecting Watershed Ecosystems through Targeted Local Land Use Policies

Land use change is the most pervasive force driving the degradation of watershed ecosystems. This article combines an econometric model of land use choice with models of watershed health indicators to examine the effects of land use policies on watershed ecosystems through their effect on land use. Our results suggest that incentive-based land use policies and property acquisition programs can have relatively large positive impacts on watershed health, while policies that change the returns to land use are less effective. The results suggest that there is potential for targeting these policies because their impacts vary across watersheds with different land use mixes.

Agrobiodiversity,farm profits and land fragmentation: Evidence from Bulgaria

This paper presents an empirical analysis of the role of land fragmentation, crop biodiversity and their interplay with farm profitability. Original primary data are drawn from a survey conducted in the Plodiv region of Bulgaria. The econometric results stress the ambiguous role of land fragmentation on farm profitability. On one hand, land fragmentation reduces farm profitability. On the other hand, land fragmentation fosters crop diversification. We also find that crop biodiversity plays a beneficial role in farm profitability. Policies that aim to increase land consolidation and reduce fragmentation may overlook the positive link between diversity and plot heterogeneity. Policies that encourage land consolidation should, therefore, consider the crucial role that this has on other variables such as farm biodiversity.     

Water Management,Spanish Irrigation Communities and Colonial Engineers

In the nineteenth century, Spanish irrigation was studied by a number of British and French engineers, who sought to acquire knowledge that could be applied to India and Algeria. In their reports, they said that Spanish irrigation communities were run by the irrigators themselves in a totally democratic way, which was not true. Although such ideas had hardly any practical consequences in colonial India and Algeria, they did have important repercussions in Spain, where the irrigation institutions came to resemble the image they had been given by the reporters, with the best results. Through the work of Elinor Ostrom, the myth created by the nineteenth‐century reporters has also eventually become an argument in favour of irrigation projects in today's developing countries being managed by water users’ associations.
