Risk adjustment, investment policy, and valuation for an unlevered firm

We characterize the optimal investment decision and the stock value of an unlevered firm that holds the non-standard option of improving the growth rate of cashflows from its assets in place upon incurring an irreversible cost. The firm's investment policy and equity price are studied as a function of the market price of risk, of cashflow's exposure to systematic risk, and of cashflow volatility.Investment, Equity pricing, Market price of risk.

Forecasting Italian Electricity Zonal Prices with Exogenous Variables

In the last few years we have observed deregulation in electricity markets and an increasing interest of price dynamics has been developed especially to consider all stylized facts shown by spot prices. Only few papers have considered the Italian Electricity Spot market since it has been deregulated recently. Therefore, this contribution is an investigation with emphasis on price dynamics accounting for technologies, market concentration and congestions. We aim to understand how technologies, concentration and congestions affect the zonal prices since these ones combine to bring about the single national price (prezzo unico d’acquisto, PUN). Hence, understanding its features is important for drawing policy indications referred to production planning and selection of generation sources, pricing and risk–hedging problems, monitoring of market power positions and finally to motivate investment strategies in new power plants and grid interconnections. Implementing Reg–ARFIMA–GARCH models, we assess the forecasting performance of selected models showing that they perform better when these factors are considered.Electricity prices, Production technologies, Market power (HHI, RSI), Congestions, Fractional Integration, Forecasting

Market access, organic farming and productivity: the determinants of creation of economic value on a sample of Fair Trade affiliated Thai farmers

We analyse the impact of Fair Trade and organic farming on a sample of Fair Trade organic rice producers in Thailand. We find that per capita income from agriculture is positively and significantly affected by organic certification and FT affiliation years. Such effect does not translate into higher productivity due to a concurring increase in worked hours. FT and organic certification contributions are however downward biased if we do not take into account the relatively higher share of self- consumption of affiliated farmers. Our main findings are robust when we control for selection bias and endogeneity with instrumental variables, propensity score matching and by restricting the sample to affiliated producers only. We also test which of the two (organic and FT) effects is stronger and find that the latter prevails.organic production, Fair Trade, productivity
