Atmospheric and Ocean Dynamics May Explain Cycles in Oceanic Oscillations
Seip, Knut Lehre; Grøn, Øyvind (Climate;Volume 7 / Issue 6, Journal article; Peer reviewed, 2019-05-29)What causes cycles in oceanic oscillations, and is there a change in the characteristics of oscillations in around 1950? Characteristics of oceanic cycles and their sources are important for climate predictability. We here ... -
Carbon dioxide precedes temperature change during short-term pauses in multi-millennial palaeoclimate records
Seip, Knut Lehre; Grøn, Øyvind; Wang, Hui (Palaeogeography, Palaeoclimatology, Palaeoecology;Volume 506, 1 October 2018, Journal article; Peer reviewed, 2018-06-19)In Antarctica, ice-core temperature has traditionally been regarded as a leading variable to carbon dioxide, CO2 during the last 400,000years before present (B.P.). This finding is in contrast to most reports on global ... -
Comparing sentiment and behavioral based leading indexes for industrial production in Germany: A novel running local test
Seip, Knut Lehre; Schröder, Michael; Yunus, Yilmaz (Working Paper;7/2017, Working paper, 2017) -
Comparing sentiment- and behavioral-based leading indexes for industrial production:When does each fail?
Seip, Knut Lehre; Yilmaz, Yunus; Schröder, Michael (Economies; Volume 7 / Issue 4, Journal article; Peer reviewed, 2019)We apply a relatively novel leading–lagging (LL) method to four leading and one lagging indexes for industrial production (IP) in Germany. We obtain three sets of results. First, we show that the sentiment-based ifo index ... -
Covariations between the Indian Oceandipole and ENSO: a modeling study
Wang, Hui; Kumar, Arun; Narapusetty, Balachandrudu; Seip, Knut Lehre (Climate Dynamics;November 2019, Volume 53, Issue 9–10, Journal article; Peer reviewed, 2019-07-11)The coevolution of the Indian Ocean dipole (IOD) and El Niño-Southern Oscillation (ENSO) is examined using both observational data and coupled global climate model simulations. The covariability of IOD and ENSO is analyzed ... -
Cycles in oceanic teleconnections and global temperature change
Seip, Knut Lehre; Grøn, Øyvind (Theoretical and Applied Climatology;, Journal article; Peer reviewed, 2018-06-11)Three large ocean currents are represented by proxy time series: the North Atlantic Oscillation (NAO), the Southern Oscillation Index (SOI), and the Pacific Decadal Oscillation (PDO).We here show how proxies for the ... -
Do Increased Tax Base and Reductions in the Underground Economy Compensate for Lost Tax Revenue Following a Tax Reduction Policy? Evidence from Italy 1982 to 2006
Orsi, Renzo; Seip, Knut Lehre (Peer reviewed; Journal article, 2023)We here examine the frequent claim that an increase in the tax base and a decrease in tax evasion will compensate for a loss in tax revenues caused by a lower tax level. Using a unique data set for the estimated underground ... -
Does employees’ compensation vary with corporate profit?
Seip, Knut Lehre; McNown, Robert (Journal article; Peer reviewed; Journal article, 2015-04)We find that from about 1965 to 1983 US employees’ compensation, EC, relative to corporate profit, CP, increases in the long run, and from 1984 to 2013 the compensation decreases relative to profit to about half its 1983 ... -
Does tax reduction have an effect on gross domestic product? An empirical investigation
Seip, Knut Lehre (Working Paper;1/2017, Working paper, 2017) -
The GDP, the US treasury yield and the federal funds rate: Who follows whom, when and why?
Seip, Knut Lehre; Zhang, Dan (Journal of Financial Economic Policy;, Peer reviewed; Journal article, 2021-06-08)Purpose: This study addresses the fundamental question on how the major players in the economy dynamically interact with each other: among the central bank, the investors in the bond market, and the firms and consumers ... -
Global lead-lag changes between climate variability series coincide with major phase shifts in the Pacific decadal oscillation
Seip, Knut Lehre; Grøn, Øyvind Geelmuyden; Wang, Hui (Peer reviewed; Journal article, 2023)We show that there are distinct periods when three ocean variability series in the Atlantic and the Pacific Oceans persistently lead or lag each other, as well as distinct periods when ocean variability series lead the ... -
The hiatus in global warming and interactions between the El Niño and the Pacific decadal oscillation: Comparing observations and modeling results
Seip, Knut Lehre; Wang, Hui (Climate;Volume 6, Issue 3, Journal article; Peer reviewed, 2018-09-04)Ocean oscillations interact across large regions; these interactions may explain cycles in global temperature anomaly, including hiatus periods. Here, we examine interaction measures and compare results from model simulations ... -
A High-Resolution Lead-Lag Analysis of US GDP, Employment, and Unemployment 1977–2021: Okun’s Law and the Puzzle of Jobless Recovery
Seip, Knut Lehre; Zhang, Dan (Economies;Volume 10 / Issue 10, Peer reviewed; Journal article, 2022)Okun’s law is formulated as the ratio between GDP and unemployment (UE): β = f(GDP/UE). It is used to investigate the relations between output and labor input across regions or across business cycles. Based on results by ... -
High-resolution lead–lag relations between Barents Sea temperatures, the AMOC and the AMO during 1971-2018
Seip, Knut Lehre; Wang, Hui (Peer reviewed; Journal article, 2023)The direction of heat transport from the atmosphere to the Barents Sea, and between the Barents Sea and the North Atlantic is important for understanding the interplay between Greenland ice melting and anthro- pogenic ... -
Investigating possible causal relations among physical, chemical and biological variables across regions in the Gulf of Maine
Seip, Knut Lehre (Hydrobiologia;744(1), Journal article; Peer reviewed, 2014-10-15)We examine potential causal relations between ecosystem variables in four regions of the Gulf of Maine under two major assumptions: (i) a causal cyclic variable will precede, or lead, its effect variable; e.g., a peak ... -
Leading the game, losing the competition: identifying leaders and followers in a repeated game
Seip, Knut Lehre; Grøn, Øyvind (Journal article; Peer reviewed, 2016)We explore a new method for identifying leaders and followers, LF, in repeated games by analyzing an experimental, repeated (50 rounds) game where Row player shifts the payoff between small and large values – a type of ... -
Maximum Northern Hemisphere warming rates before and after 1880 during the Common Era
Seip, Knut Lehre; Wang, Hui (Theoretical and Applied Climatology;, Peer reviewed; Journal article, 2023)We find that maximal decadal Northern Hemisphere warming increases as rapidly before as after the industrial revolution (0.86 °C decade−1 before 1880 and 0.60–0.68 °C decade−1 after 1880). However, whereas the number of ... -
