Electronic auction markets collect large amounts of auction field data. This enables a structural estimation of the bid distributions and the possibility to derive optimal reserve prices. In this paper we propose a new approach to setting reserve prices. In contrast to traditional auction theory we use the buyer’s risk statement for getting a winning bid as a key criterion to set an optimal res...

Nome placer offshore gold grade estimation is a challenging problem in light of extreme ore heterogeneity. However, this type of phenomenon is quite common in placer ore grade variation. Further, the characterization of spatial ore grade variability and subsequent ore grade modelling of the deposit becomes problematic due to the unavailability of adequate samples. Being located in the Arctic, t...

The growth in the importance of interruptible sources of energy is increasing the concerns of many electricity market regulators with respect to the reliability and stability of electricity supply. Decisions such as that to increase the number of reserve markets, their reserve requirements, or the role of reserve prices in the final electricity price have meant that generation plants are curren...

in this paper, we will review the foreign exchange market and will try to extract an exchange market pressure and an intervention index for iran by following the weymark (1995) approach to evaluate the central bank of iran’s exchange rate policy during 1368:q1 to 1391:q3. the estimation method employed, is the econometric technique known in the literature as the two-stage least squares (2sls).t...

This paper estimates the parameters of a stochastic growth model with asset market and contrasts the model's moments with moments of the actual data. We solve the model through log-linearization along the line of Campbell (1994) and estimate the model without and with asset pricing restrictions. As asset pricing restrictions we employ the risk-free interest rate and the Sharpe-ratio. To estimat...

This paper provides a complete program for the valuation of aggregate non-life insurance liability cash flows based on claims triangle data. The valuation is fully consistent with the principle of valuation by considering the costs associated with a transfer of the liability to a so-called reference undertaking subject to capital requirements throughout the runoff of the liability cash flow. Th...

By introducing the practical application of grade equivalent theory in a copper -cobalt mine, it can show maximum economic value individual ore block and maximize comprehensive utilization limited resources contains positive significance for extending service life mine. Briefly steps Micromine software process reserve estimation feasibility displaying blocks. Estimation be completed objectively...

OBJECTIVES This study sought to determine the feasibility of coronary sinus flow velocity analysis by transesophageal Doppler echocardiography for estimation of coronary flow reserve in patients with syndrome X and patients with coronary artery disease. BACKGROUND Coronary flow reserve provides useful information in patients with coronary artery disease and patients with syndrome X. Current m...
