Abstract Previous research proposed two future net discount rate estimators that improved on naïve long-term average and random walk estimators. The proposed estimators were superior in the class of estimators that used only current and past observations on net discount rates. In this paper we consider two extensions. First we examine whether professional forecasts perform significantly better than the two alternatives. Second, we examine the properties and performance of multivariate estimators that account for the potentially differing time-series behaviors of the underlying wage growth and interest rate series.

This chapter aims to provide a unified theoretical foundation to the term structure of discount rates. To do this the chapter develops a benchmark model based on two assumptions: individual preferences toward risk, and the nature of the uncertainty over economic growth. Previously, it was shown that constant relative risk aversion, combined with a random walk for the growth of log consumption, yields a flat term structure for efficient discount rates. In this chapter, these two assumptions are relaxed by using a stochastic dominance approach. Stochastic models of economic growth with mean-reversion, Markov switches, and parametric uncertainty all exhibit some forms of positive statistical dependence of successive growth rates. Because this tends to magnify the long-term risk, it is the driving force of the decreasing nature of the term structure.

One of the principal problem in contemporary macroeconomics is concerned with factors increasing or decreasing economic dynamics. The mainstream approach is based on neoclassical assumptions, but recently new approaches appear mostly based on new Keynesian concepts. In present time the influence of monetary market and credit instruments become more and more significant. Credit resources of banking and financial structures can affect and distort to reallocation of resources for national and even for global economic. In present paper an empiric and econometric analysis for some macroeconometric and monetary indices for Russian Federation is done. An econometrical models describing the influence of credit variables onto real GDP is estimated. It is shown that in short-term periods changes in credit variables do influence significantly onto GDP. It is shown that on short-term periods changes in money aggregate M2 brings influence (through credit variables) onto national output. As well it is shown that changes in short-term interest rate brings significant negative influence onto real output. Impulse response functions for GDP on shocks of credit variables, monetary base and short-term interest rate are evaluated. For the present study of credit cycles and their impact to real business cycles statistical data (quarterly time series) on the following factors for Russian Federation are collected: nominal and real GDP, monetary base M2, short-term interest rate, long-term interest rate (10-year treasuries bill rate), total debt outstanding. All time series are seasonally adjusted and collected for the period 2004 Q1 - 2013 Q2. All interest rates are adjusted for inflation (i.e. we deal with real interest rates). The investigation of long-term relationship for the factors under consideration are based on integration. It is important to note that in the present paper all econometric models are estimated on "pure" statistical data, while in many research papers on business and credit cycles all evaluations and inferences are based on "filtered" time series (mostly filtered by Hodrick-Prescott's method). In present paper "causality" always means "Granger causality". All estimations are made in gretl, an open-source multiplatform econometric software.

Abstract. This study investigates the long-term evolution of subtropical ozone profile time series (1999–2010) obtained from ground-based FTIR (Fourier Transform InfraRed) spectrometry at the Izaña Observatory ozone super-site. Different ozone retrieval strategies are examined, analysing the influence of an additional temperature retrieval and different constraints. The theoretical assessment reveals that the FTIR system is able to resolve four independent ozone layers with a precision of better than 6% in the troposphere and of better than 3% in the lower, middle and upper stratosphere. This total error includes the smoothing error, which dominates the random error budget. Furthermore, we estimate that the measurement noise as well as uncertainties in the applied atmospheric temperature profiles and instrumental line shape are leading error sources. We show that a simultaneous temperature retrieval can significantly reduce the total random errors and that a regular determination of the instrumental line shape is important for producing a consistent long-term dataset. These theoretical precision estimates are empirically confirmed by daily intercomparisons with Electro Chemical Cell (ECC) sonde profiles. In order to empirically document the long-term stability of the FTIR ozone profile data we compare the linear trends and seasonal cycles as obtained from the FTIR and ECC time series. Concerning seasonality, in winter both techniques observe stratospheric ozone profiles that are typical middle latitude profiles (low tropopause, low ozone maximum concentrations) and in summer/autumn profiles that are typical tropical profiles (high tropopause, high maximum concentrations). The linear trends estimated from the FTIR and the ECC datasets agree within their error bars. For the FTIR time series, we observe a significant negative trend in the upper troposphere/lower stratosphere of about −0.2% yr−1 and a significant positive trend in the middle and upper stratosphere of about +0.3% yr−1 and +0.4% yr−1, respectively. Identifying such small trends is a difficult task for any measurement technique. In this context, super-sites applying different techniques are very important for the detection of reliable ozone trends.

Abstract The study explores time series properties of three wage net discount rate series derived using interest rates based on (alternatively) 1-year, 6-month and 3-month Treasury securities coupled with wage growth rates, initially for the period from 1981:01 to 2012:06, then subsequently through 2012:12. Stationarity tests are run on the full series and various sub-series to identify any portion of the series on which reliable forecasting can be based. Initially no support is found for the total offset hypothesis based on the full-time series (but support is subsequently found for total offset when exploring various data sub-series). Positive findings include that the three trended wage net growth rate series for the entire period under study are stationary, implying that reliable short-term forecasting of wage net discount rates is possible based on each of the trended series. Short-run forecasts based on the trended series are presented for 2012:07–2012:12 and compared to actual data in the period. Finally, the three trended wage net discount rate series are re-examined for 1981:01–2012:12, with short-term forecasting equations presented. Various sub-series of WNDRs are then explored in hopes of finding one or more that may be stationary about a constant term. Additional testing identifies three sub-series all ending 2012:12 with varying start dates that have desirable stationarity properties. The sub-series starting 2007:11 is highly stationary, but peculiar, with an associated constant WNDR that is negative and statistically different from zero; and the two sub-series beginning 1990:12 and 1994:05 have stationary attributes, yet possess constant terms that are slightly positive but not statistically different from zero, thus providing modest support for the total offset method.

National Oceanic and Atmospheric Administration–Advanced Very High Resolution Radiometer (NOAA-AVHRR) data provides the possibility to build the longest Land Surface Temperature (LST) dataset to date, starting in 1981 up to the present. However, due to the orbital drift of the NOAA platforms, no LST dataset is available before 2000 and the arrival of newer platforms. Although numerous methods have been developed to correct this orbital drift effect on the LST, a lack of validation has prevented their application. This is the gap we bridge here by using the 15 min temporal resolution of Meteosat Second Generation–Spinning Enhanced Visible and Infra-Red Imager (MSG-SEVIRI) data to simulate drifted and reference LST time series. We then use these time series to validate an orbital drift correction method based on solar zenith angle (SZA) anomalies that we presented in a previous work (C1), as well as two variations of this approach (C0 and C2). Our results show that the C0 method performs better than the two others, although its overall bias absolute value ranges up to 1 K, while standard deviation values remain around 3 K. This is verified for most land covers, for all NOAA platforms, and these statistics remain mostly stable with noise on SZA time series (from 0° to ±10°). With this study, we show that orbital drift correction methods can be thoroughly validated and that such validation should aim toward bias absolute values below 0.1 K and standard deviation values around 1.4 K at coarse spatial resolution. To validate other orbital drift correction approaches, the drifted and reference time series used in this work are freely available for download from the first author’s webpage. This will be the first step toward the building of an orbital-drift-corrected long-term LST dataset.

Abstract Research background: An investment appraisal applies a single discount rate across all effects. However, this may be insufficient for heterogenous environmental impacts, mixing private and public goods as well as use and non-use values, where individuals may have multiple intertemporal preferences due to their duality to act as consumer or citizen. Purpose: The paper aims at identifying the scope of discrepancies in the level of discount rate for public and private as well as use-and non-use investment gains. Research methodology: The contingent valuation method is used to elicit stated discount rates for 2 hypothetical investments: environmental or financial gains to distinguish between public and private domain accompanied by two time-frames: short (use values) and long (non-use values). Results: The discount rate for the environment is lower than for money. It is also lower for the long-term horizon in comparison with the short-term perspective. The discrepancies are observed also for explanatory variables in respect to a socio-economic profile and attitude characteristics. Novelty: The paper adds to the discussion on valuation discrepancies between self-interested consumers and socially oriented citizens. The scarcity of previous research examining discount rates for public/private goods as well as the short/long-time horizon make the results relevant for public policy dealing with climate change and environmental protection, providing an insight into individual intertemporal preferences.
