Streszczenie:
The Japan Electric Power Exchange (JEPX) provides a platform for the trading of electric energy in a manner similar to more traditional financial markets. As the number of market agents increase, there is an increasing need for effective price-forecasting models. Electricity price data are observed to exhibit periods of relatively stable, i.e., low-magnitude, low-variance prices interspersed with periods of higher prices accompanied by larger uncertainty. The price data time series therefore exhibits a temporal non-stationarity characteristic that is difficult to capture with typical time seri

This paper proposes a new hybrid model to forecast electricity market prices up to four days ahead. The components of the proposed model are combined in two dimensions. First, on the “vertical” dimension, long short-term memory (LSTM) neural networks and extreme gradient boosting (XGBoost) models are stacked up to produce supplementary price forecasts. The final forecasts are then picked depending on how the predictions compare to a price spike threshold. On the “horizontal” dimension, five models are designed to extend the forecasting horizon to four days. This is an important requirement to

This research proposes an investigative experiment employing binary classification for short-term electricity price spike forecasting. Numerical definitions for price spikes are derived from economic and statistical thresholds. The predictive task employs two tree-based machine learning classifiers and a deterministic point forecaster; a statistical regression model. Hyperparameters for the tree-based classifiers are optimized for statistical performance based on recall, precision, and F1-score. The deterministic forecaster is adapted from the literature on electricity price forecasting for th

Large price fluctuations have become a significant character and impede resource allocation in the electricity market. Negative prices and peak load spike prices coexist and represent over-supply and over-demand, respectively. It is important to interpret the impact of these extreme prices on sustainable power management from the perspective of economics. In this paper, we build a principal component analysis (PCA) to assess the impact of the two opposite phenomena on the smart grid electricity system.

This article examines how electricity market liquidity, renewable production and cross-border activity together in combination explain price spikes in the Hungarian Power Exchange day-ahead auctions. In the applied logit model, the dependent variable representing the price spike is binary, and the key explanatory variable is a modified bid-ask spread depicting liquidity. Weather-dependent renewable production and the difference between exports and imports appear as control variables in the model. The empirical analysis was based on data from 2017 and 2018.

Abstract Existing micro evidence of firms’ price changes tends to show a downward sloping hazard rate – the longer the price of a product has remained the same, the less likely it is that the price will change. Using a panel of Norwegian plant- and product-specific prices, we also find a downward sloping hazard when applying a Kaplan–Meier model. After having controlled for both observed and unobserved characteristics, we find flat hazards with spikes in the first and twelfth months. This suggests time-dependent price-setting by at least some of the producers. The spike after 12 months might b

Specifically, we study events of the form P ( LMP ∉ ∏ i = 1 n [ α i − , α i + ] ) , where LMP is the vector of LMPs at the n power grid nodes, and α − , α + ∈ R n are vectors of price thresholds specifying undesirable price occurrences. By exploiting the structure of the supply–demand matching mechanism in power grids, we look at LMPs as deterministic piecewise affine, possibly discontinuous functions of the stochastic input process, mode

Changes in tastes and political climates in Europe caused the profitability of the spices to fall precipitously. This led the VOC and the EIC to seek new markets including cotton, coffee, opium and tea. It was in the middle of the seventeenth century that European interest in spices began to wane. In fact, there was an oversupply of pepper by mid-century, which dropped prices by about 40% compared with that which the Portuguese and then the VOC had long been able to mainta

Streszczenie:
Contrary to the opinions expressed by many commentators, the recent price spike in agricultural commodities is a transitory phenomenon. Using projections from SIMPLE – a global model of the farm and food system – we argue that, in the long run, food prices will most likely resume their historical downward trend. We begin with an evaluation of the historical period 1961 to 2006 wherein the growth in agricultural productivity outpaced that of global crop demand, the latter being fueled by rising population and incomes. As a consequence, we observed a historical decline in global crop prices, whi

Lavender oil obtained from the flowers of English lavender (Lavandula angustifolia Mill., Lamiaceae) is widely used in the production of fragrances, cosmetics, food, beverage products, and pharmaceuticals. The essential oil (EO) is used orally, by inhalation as a sleep aid, and can be applied topically for skin treatment. Adulteration of lavender oil is considered to be widespread due to high product demand and lower prices for chemically similar EOs and compounded fragrances. Some of the known adulterants are EOs from spike lavender (Lavandula latifolia Medik.) or lavandin (Lavandula × interm

In spite of popularity of the Gaussian distribution in financial modeling, we demonstrated that Levy’s stable distribution is more suitable due to its theoretical reasons and analysis results. We study the possibility of construction indicators- precursors relying on one of the most power-law tailed distributions - Levy’s stable distribution. Here, we apply moving window based procedure for calculation of Levy’s parameters - a - stability and /?- skewness for daily values of Dow Jones Industrial Average (from 1 March 2000 to 28 March 2019), the gold price (from 1 April 1968 to 8 May 2019) and

Over the past three years, there has been a convergence of interest in the global farm and food system and its contributions to feeding the world’s population as well as to ensuring the environmental sustainability of the planet. The 2007/2008 commodity crisis underscored the vulnerability of the global food system to shocks from extreme weather events, energy and financial markets, as well as government interventions in the form of export bans and other measures designed to avoid domestic adjustment to global scarcity. We have learned that a “perfect storm” in which all these factors coincide

We examine real and financial spillovers to safe haven financial flow destinations due to risk-off shocks in global financial markets. Using country-specific structural vector autoregression models over the period 1990 to 2021, we show that dynamics for Japan appear to be different to those of Switzerland and the United States in four main ways. First, in response to risk-off episodes over the estimation period, the yen real effective exchange rate appreciates sharply and significantly, with the effect persisting over time. Second, no significant effects on portfolio flows to Japan are found,
