  text: "Many of the major international and intrastate crises and conflicts, but
    also the threat to democratic principles, are driven by belief systems and ideologies.
    They fuel political polarization, which is particularly evident in the battleground
    of social media. Nevertheless, we hardly pay attention to ideologies, their narratives,
    functions and organizations in economic theory today. Ideologies as “non-rational
    beliefs” seem incompatible with rationality in economic models. \r\n\r\nTherefore,
    the book examines the role of ideologies and belief systems in individual decision-making
    behavior from an economic and rational perspective. Due to the fact that people
    have incomplete information, belief systems and ideologies fulfill a number of
    important functions. While ideologies themselves serve psychological needs, they
    are used as a cognitive framework for rational decision-making once they have
    been adopted through a Bayesian learning process. They influence decisions in
    a wide range of areas, from consumption and work to politics. This is where the
    role of ideological organizations becomes important, because they determine the
    ideological direction of the narratives and their dissemination. \r\n\r\nThus,
    ideologies give a normative direction, for better or for worse. The “quality”
    of ideological leadership can be evaluated normatively on the basis of principles
    such as individual sovereignty and human dignity. A democratic discourse requires
    an information and communication system that enables an evaluation of precisely
    these ideologies, free from resource and information power.\r\n"

  text: We propose an indicator for detecting anomalous stock market valuation in
    real time such that market participants receive timely signals so as to be able
    to take stabilizing action. Unlike existing approaches, our anomaly indicator
    introduces three methodological novelties. First, we use an endogenous, purely
    data-driven, nonparametric trend identification method to separate long-term market
    movements from more short-term ones. Second, we apply SETAR models that allow
    for asymmetric expansions and contractions around the long-term trend and find
    systematic stock price cycles. Third, we implement these findings in our indicator
    and conduct real-time market forecasts, which have so far been neglected in the
    literature. Applications of our indicator using monthly S&P 500 stock data from
    1970 to the end of 2022 show that short-term anomalous market movements can be
    identified in real time up to one year ahead. We predict all major anomalies,
    including the 1987 Bubble and the initial phase of the Financial Crisis that began
    in 2007. In total, our anomaly indicator identifies more than 80% of all – even
    minor – anomalous episodes. Thus, smoothing market exaggerations through early
    signaling seems possible.

  text: '<jats:p>Is Artificial Intelligence a more significant invention than electricity?
    Will it result in explosive economic growth and unimaginable wealth for all, or
    will it cause the extinction of all humans? Artificial Intelligence: Economic
    Perspectives and Models provides a sober analysis of these questions from an economics
    perspective. It argues that to better understand the impact of AI on economic
    outcomes, we must fundamentally change the way we think about AI in relation to
    models of economic growth. It describes the progress that has been made so far
    and offers two ways in which current modelling can be improved: firstly, to incorporate
    the nature of AI as providing abilities that complement and/or substitute for
    labour, and secondly, to consider demand-side constraints. Outlining the decision-theory
    basis of both AI and economics, this book shows how this, and the incorporation
    of AI into economic models, can provide useful tools for safe, human-centered
    AI.</jats:p>'

  text: "<jats:title>Abstract</jats:title>\r\n               <jats:p>This book combines
    theoretical and empirical research across various academic disciplines, including
    economics, psychology, neuroscience, philosophy, and political science, to describe
    why individuals adopt political ideologies and how this choice can potentially
    exacerbate conflict and violence. Ideology is particularly important to conflict.
    Data on intra- and international conflict shows that the number of ideologically
    driven conflicts has increased tremendously in recent decades. Although some researchers
    have started to investigate extensively the link between ideology and conflict,
    they struggle to find holistic explanations through which ideologies might shape
    conflict. This book addresses this effort by providing an interrelated multidisciplinary
    framework to explain the multidimensional functions of ideology. It illustrates
    that ideologies are not only capable of shaping conflictual behavior or mobilizing
    political actors, but also of addressing human needs, desires, and preferences.
    Hence, this book seeks to explain how individuals adopt ideologies that match
    their underlying needs and preferences; that ideologies have the capacity to reconcile
    deprived psychological human needs; and that radical groups and organizations
    use ideologies to recruit individuals and pursue their objectives. To understand
    these relationships better and to apply the theoretical background to real-world
    situations, we include real-life cases that describe how depriving individuals
    of resources that satisfy their underlying needs and preferences can lead them
    to adopt particular ideologies that are disseminated by radical groups or organizations.
    These radical groups or organizations then make decisions, which can potentially
    lead to conflict onset and continuous long-term struggles.</jats:p>"

  text: 'Individuals strive to make decisions that are consistent with not only their
    consumer preferences but also their psychological needs. However, they are confronted
    with complex, ambiguous or even false information. Ideologies and belief systems
    provide guidance when processing and evaluating information and give a coherent
    and comprehensible interpretation of reality. The first question is: why is an
    individual attracted to a particular ideology? Individuals choose ideologies that
    resonate with their subjective psychological needs and preferences. Second, how
    do individuals search for ideologies and find out which suit them best? We model
    an individual’s sequential information search for the best matching ideologies
    by applying Bayesian learning and utility optimization. Additional information
    enhances utility by reducing uncertainty. As a search is costly, the process may
    stop once an individual adopts an ideology even if the information set remains
    incomplete. Third, once they have chosen a particular ideology, individuals adhere
    to its rules and norms when making everyday decisions. Consumers not only physically
    consume, but they also act in accordance with their psychological needs.'

  text: <jats:title>Abstract</jats:title><jats:p>The ability of various policy activities
    to reduce the reproduction rate of the COVID-19 disease is widely discussed. Using
    a stringency index that comprises a variety of lockdown levels, such as school
    and workplace closures, we analyze the effectiveness of government restrictions.
    At the same time, we investigate the capacity of a range of lockdown measures
    to lower the reproduction rate by considering vaccination rates and testing strategies.
    By including all three components in an SIR (Susceptible, Infected, Recovery)
    model, we show that a general and comprehensive test strategy is instrumental
    in reducing the spread of COVID-19. The empirical study demonstrates that testing
    and isolation represent a highly effective and preferable approach towards overcoming
    the pandemic, in particular until vaccination rates have risen to the point of
    herd immunity.</jats:p>

  text: <jats:title>Abstract</jats:title><jats:p>We provide a partial equilibrium
    model wherein AI provides abilities combined with human skills to provide an aggregate
    intermediate service good. We use the model to find that the extent of automation
    through AI will be greater if (a) the economy is relatively abundant in sophisticated
    programs and machine abilities compared to human skills; (b) the economy hosts
    a relatively large number of AI-providing firms and experts; and (c) the task-specific
    productivity of AI services is relatively high compared to the task-specific productivity
    of general labor and labor skills. We also illustrate that the contribution of
    AI to aggregate productive labor service depends not only on the amount of AI
    services available but on the endogenous number of automated tasks, the relative
    productivity of standard and IT-related labor, and the substitutability of tasks.
    These determinants also affect the income distribution between the two kinds of
    labor. We derive several empirical implications and identify possible future extensions.</jats:p>

  text: <jats:title>Abstract</jats:title><jats:p>Using data from the German Socio-Economic
    Panel for 1984–2018, we analyze the intergenerational education mobility of immigrants
    in Germany by identifying the determinants of differences in educational stocks
    for first- and second-generation immigrants in comparison to individuals without
    a migration background. Our results show that on average, first-generation immigrants
    have fewer years of schooling than native-born Germans and have a disproportionate
    share of lower educational qualifications. This gap is strongly driven by age
    at immigration, with immigration age and education revealing a nonlinear relationship.
    While the gap is relatively small among individuals who migrate at a young age,
    integrating in the school system at secondary school age leads to large disadvantages.
    Examining the educational mobility of immigrants in Germany, we identify an inter-generational
    catch-up in education. The gap in education between immigrants and natives is
    reduced for the second generation. Finally, we find that country of origin differences
    can account for much of the education gap. While immigrants with an ethnic background
    closer to the German language and culture show the best education outcomes, immigrants
    from Turkey, Italy, and other southern European countries and especially the group
    of war refugees from Syria, Afghanistan, Iraq and other MENA countries, have the
    lowest educational attainment.</jats:p>

  text: <jats:title>Abstract</jats:title><jats:p>Using time series data for the period
    1959–2015, our empirical analysis examines the simultaneous effects of the individual
    components of the global carbon budget on temperature. Specifically, we explore
    the possible effects of carbon emissions caused by fossil fuel combustion, cement
    production, land-use change emissions, and carbon sinks (here in terms of land
    sink and ocean sink) on climate change. The simultaneous inclusion of carbon emissions
    and carbon sinks allows us to look at the coexistent and opposing effects of the
    individual components of the carbon budget and thus provides a holistic perspective
    from which to explore the relationship between the global carbon budget and global
    warming. The results reveal a significant positive effect of carbon emissions
    on temperature for both fossil fuels emissions and emissions from land-use change,
    confirming previous results concerning carbon dioxide and temperature. Further,
    while ocean sink does not seem to have a significant effect, we identify a temperature-decreasing
    effect for land sink.</jats:p>

  text: <jats:title>Abstract</jats:title><jats:p>Vaccinations, lockdowns and testing
    strategies are three potential elements of an effective anti-coronavirus, and
    in particular Covid-19, health policy. The following analysis considers - within
    a simple model - the potentially crucial role of a Corona testing approach in
    combination with a quarantine approach which is shown herein to be a substitute
    for broad lockdown measures. The cost of lockdowns/shutdowns are rather high so
    that – beyond progress in terms of a broad vaccination program – a rational testing
    strategy should also be carefully considered. Testing has to be organized on the
    basis of an adequate testing infrastructure which could largely be implemented
    in firms, schools, universities and public administration settings. As regards
    the cost of a systematic broad Covid-19 testing strategy, these could come close
    to 0.5% of national income if there are no vaccinations. The Testing &amp; Quarantine
    approach suggested here – with tests for symptomatic as well as asymptomatic people
    - is based on a random sampling and would require rather broad and frequent testing;
    possibly one test per person every 7–10 days. At the same time, one should consider
    that the cost of further lockdowns/shutdowns of a duration of 1 month could be
    very high, such that a standard cost benefit analysis supports the testing approach
    suggested herein. Also, an optimal policy mix could be designed where both vaccinations
    and testing play a crucial role. As of late January 2021, no further lockdowns
    in Germany and other OECD countries would be necessary if a broad testing infrastructure
    can be established rather quickly. This in turn will reinforce economic optimism
    and help to jumpstart economic growth in Europe, the US and Asia in a solid way.
    The basic logic of the testing approach pointed out here for industrialized countries
    could also be applied in developing countries. The approach presented is complementary
    to the IMF analysis of Cherif/Hasanov.</jats:p>

  text: <jats:title>Abstract</jats:title><jats:p>In light of the COVID-19 pandemic,
    we scrutinize what has been established in the literature on whether entrepreneurship
    can cause and resolve extreme events, the immediate and long-run impacts of extreme
    events on entrepreneurship, and whether extreme events can positively impact (some)
    entrepreneurship and innovation. Based on this, we utilize a partial equilibrium
    model to provide several conjectures on the impact of COVID-19 on entrepreneurship,
    and to derive policy recommendations for recovery. We illustrate that while entrepreneurship
    recovery will benefit from measures such as direct subsidies for start-ups, firms’
    revenue losses, and loan liabilities, it will also benefit from aggregate demand-side
    support and income redistribution measures, as well as from measures that facilitate
    the innovation-response to the Keynesian supply-shock caused by the pandemic,
    such as access to online retail and well-functioning global transportation and
    logistics.</jats:p>
