Financial crises in Spain: lessons from the last 150 years
2012
Financial crises are not unique to current financial systems. Are crises alike? Have they become more frequent, longer lasting and more severe since the 20th century? What does history tell us? The objective of this paper is to study the financial crises that have occurred in Spain over the last 150 years. We consider different types of crises (banking, currency and stock market crises), together with all their possible combinations, estimate their frequency by period and measure their length and depth. The main conclusion we obtain is that Spanish crises have been more frequent than in the rest of the world and have been more severe and more complex since 1973, as the 2007 crisis is confir…
- STRATEGIC PIGOUVIAN TAXATION, STOCK EXTERNALITIES AND POLLUTING NON-RENEWABLE RESOURCES
2001
This paper extends Wirl and Dockner¿s (1995) model designed to analyze the long-term bilateral interdependence between a resource exporting cartel and a coalition of resource importing country governments. Firstly, depletion effects are introduced into the analysis of the intertemporal properties of a pigouvian tax. Secondly, the feedback Stackelberg equilibria are computed. The results show that the dynamics of the tax depends critically on the level of the marginal environmental damage. Moreover, they also show that the tax defined by the Markov-perfect Nash equilibrium is a neutral pigouvian tax in the sense that it only corrects the market inefficiency caused by the stock externality.

Akciju tirgus ietekme uz ekonomiku. Specifika un attīstības tendencies.
2021
Promocijas darbā tiek pētīta akciju tirgus ietekme uz ekonomiku S & P 500 indeksa piemērā un makroekonomiskie rādītāji ar pētījumu jautājumu par to, vai akciju tirgu var uztvert kā vienu no vadošajiem ekonomikas barometriem. Teorija novēroja pieejamo literatūru par akciju tirgus darbību, tās līdzīgo attīstību un ekonomiskajiem cikliem, iepriekšējo pētījumu analīzi par akciju tirgus un makroekonomisko rādītāju attiecībām. Analītiskā daļa palīdzēja apkopot ceturkšņa datus starp 2014. -2019. Lai gan empīriskā daļa noslēdz pētījumu ar statistiskiem aprēķiniem. Tādējādi savukārt reālais iekšzemes kopprodukts (IKP) un patēriņa cenu indekss (PCI) ir spēcīgākie pozitīvi korelētie un statistiski noz…
Emerging Market Contagion Under Geopolitical Uncertainty
2019
We find that 10 emerging stock markets have high risk of contagion on the regional level but lower spillover with respect to the global markets, implying a potential for diversification benefits between emerging and global markets. Regional market integration seems to have been caused by trade integration, which has a policy implication for trade agreements’ systemic risk effects. We find that the geopolitical risk has no impact on either the return, or volatility spillovers. However, the general stock market risk (VIX) is connected to individual market volatilities, while the oil market is largely receiving the spillovers from the other markets. peerReviewed
The determinants of employees’ investments in their company share
2007
Our research is motivated by an observation. Employee Ownership is a form of savings that is becoming moreand more sought after these days. The concentration of the employee savings into employee ownership isbecoming stronger. These evolutions translate into a fact: employees facing a savings menu tend to chooseEmployee Ownership. The high exposure to risk of the employee-shareholders might have some consequence fortheir assets and their job. For companies, the cost of this exposure to risk can also be high. These observationshave led us to wonder about the causes of employees’ investments in their company stock. Thus, this researchtries to answer the question: Which are determinants of emp…
DRIFTS Sensor: Soil Carbon Validation at Large Scale (Pantelleria, Italy)
2013
A fast and accurate measurement of soil carbon is needed in current scientific issues. Today there are many sensors suitable for these purposes, but choosing the appropriate sensor depends on the spatial scale at which the studies are conducted. There are few detailed studies that validate these types of measures allowing their immediate use. Here it is validated the quick use of a sensor in execution at Pantelleria, chosen for size, use and variability of the parameter measured, to give an operational tool for carbon stocks studies. The DRIFT sensor used here has been validated in the first 60 cm of the soil of the whole island, and it has shown predictivity higher than 90%.
Describing urban soils through a faceted system ensures more informed decision-making
2016
Urban areas are increasing worldwide at a dramatic rate and their soils definitely deserve more attention than they have received in the past. In urban environments, soils potentially provide the same ecosystem services as in rural and wild environments, although in some cases they are depleted of their basic functions, such as when they lose their productive and filtering capacities because of sealing, and become mere supports for infrastructures. In other cases, soils of urban areas acquire new functions that are unique to these environments. Current soil classifications fail to effectively account for the complexity of urban soils and the information that is required for their management…
The COVID-19 Impact on Bucharest Stock Exchange. The First Six Months
2020
Abstract The first case of coronavirus was registered in Romania on February 26. From this moment, Romania has become “infected”, just like the whole world, and the economy has suffered milder or more severe symptoms, depending on the activity field. Four months have passed since then, during which in Romania, the effects of the health crisis overlapped with a tense political situation, in an unfavorable economic context. Once the COVID-19 hits each country, the economic effects started to become visible in all the world’s financial markets, the financial market being among the first to suffer the impact of the COVID-19 crisis. This paper analyzes how the financial market in Romania was aff…
The impact of soil erosion on soil fertility and vine vigor. A multidisciplinary approach based on field, laboratory and remote sensing approaches
2018
Soil erosion processes in vineyards, beyond surface runoff and sediment transport, have a strong effect on soil organic carbon (SOC) loss and redistribution along the slope. Variation in SOC across the landscape can determine differences in soil fertility and vine vigor. The goal of this research was to analyze the interactions among vines vigor, sediment delivery and SOC in a sloping vineyard located in Sicily. Six pedons were studied along the slope by digging 6 pits up to 60 cm depth. Soil was sampled every 10 cm and SOC, water extractable organic carbon (WEOC) and specific ultraviolet absorbance (SUVA) were analyzed. Erosion rates, detachment and deposition areas were measured by the po…
Long-term effects of contrasting tillage on soil organic carbon, nitrous oxide and ammonia emissions in a Mediterranean Vertisol under different crop…
2018
This 2-year study aimed to verify whether the continuous application of no tillage (NT) for over 20 years, in comparison with conventional tillage (CT), affects nitrous oxide (NO) and ammonia (NH) emissions from a Vertisol and, if so, whether such an effect varies with crop sequence (continuous wheat, WW and wheat after faba bean, FW). To shed light on the mechanisms involved in determining N-gas emissions, soil bulk density, water filled pore space (WFPS), some carbon (C) and nitrogen (N) pools, denitrifying enzyme activity (DEA), and nitrous oxide reductase gene abundance (nosZ gene) were also assessed at 0–15 and 15–30 cm soil depth. Tillage system had no significant effect on total NH e…
