This research paper focuses on investigating the dynamics of firm size transition and its impact on job creation in China. The authors propose a Markov-chain-based descriptive approach to analyze the firm-level panel data extracted from the Chinese Industrial Enterprises Database for the period 1998-2013. The study begins by emphasizing the importance of social employment carried out by firms in determining a country's prosperity and stability. The fluctuations in firm employment reflect the process of job creation or destruction, making it crucial to understand firm size dynamics. The proposed method allows for a clear demonstration of how firms transition between different size categories over short time periods. By utilizing Markov transfer matrices, the researchers introduce two key measures: transition trend and transition entropy. These measures help reveal the tendency of firm size transfer between small, medium, and large firms, as well as quantify the uncertainty of size change. The findings indicate that small and medium manufacturing firms in China have greater job creation potentials compared to large firms during this time period. However, there are some limitations to consider. Firstly, the proposed method is only applicable for describing past events and lacks predictive capabilities. Additionally, there is limited prior research on using Markov chains to fully investigate job creation issues. Therefore, further discussion is needed regarding the applicability of Markov chains for empirical analysis and forecasting under different circumstances. Furthermore, the classification standard used to categorize firm sizes may not be optimal for describing small firms accurately. While it aligns with a log-normal function based on previous research, alternative standards could provide better insights into small firm categories. In conclusion, this research provides valuable insights into understanding firm size dynamics and their implications for job creation in China. The proposed descriptive approach using Markov chains offers intuitive demonstrations of firm size transitions and helps quantify uncertainty.

    Bounds on Distributional Treatment Effect Parameters using Panel Data with an Application on Job Displacement
    Brantly Callaway · 2020 · Econometrics · AI summary available
    Abstract

    This paper develops new techniques to bound distributional treatment effect parameters that depend on the joint distribution of potential outcomes -- an object not identified by standard identifying assumptions such as selection on observables or even when treatment is randomly assigned. I show that panel data and an additional assumption on the dependence between untreated potential outcomes for the treated group over time (i) provide more identifying power for distributional treatment effect parameters than existing bounds and (ii) provide a more plausible set of conditions than existing methods that obtain point identification. I apply these bounds to study heterogeneity in the effect of …

    Deep Learning Macroeconomics
    Rafael R. S. Guimaraes · 2022 · Econometrics · AI summary available
    Abstract

    Limited datasets and complex nonlinear relationships are among the challenges that may emerge when applying econometrics to macroeconomic problems. This research proposes deep learning as an approach to transfer learning in the former case and to map relationships between variables in the latter case. Although macroeconomists already apply transfer learning when assuming a given a priori distribution in a Bayesian context, estimating a structural VAR with signal restriction and calibrating parameters based on results observed in other models, to name a few examples, advance in a more systematic transfer learning strategy in applied macroeconomics is the innovation we are introducing. We expl…

    On Bayesian Filtering for Markov Regime Switching Models
    Nigar Hashimzade, Oleg Kirsanov, Tatiana Kirsanova et al. · 2024 · Econometrics · AI summary available
    Abstract

    This paper presents a framework for empirical analysis of dynamic macroeconomic models using Bayesian filtering, with a specific focus on the state-space formulation of Dynamic Stochastic General Equilibrium (DSGE) models with multiple regimes. We outline the theoretical foundations of model estimation, provide the details of two families of powerful multiple-regime filters, IMM and GPB, and construct corresponding multiple-regime smoothers. A simulation exercise, based on a prototypical New Keynesian DSGE model, is used to demonstrate the computational robustness of the proposed filters and smoothers and evaluate their accuracy and speed for a selection of filters from each family. We show …

    Modeling Macroeconomic Variations After COVID-19
    Serena Ng · 2021 · Econometrics · AI summary available
    Abstract

    The coronavirus is a global event of historical proportions and just a few months changed the time series properties of the data in ways that make many pre-covid forecasting models inadequate. It also creates a new problem for estimation of economic factors and dynamic causal effects because the variations around the outbreak can be interpreted as outliers, as shifts to the distribution of existing shocks, or as addition of new shocks. I take the latter view and use covid indicators as controls to 'de-covid' the data prior to estimation. I find that economic uncertainty remains high at the end of 2020 even though real economic activity has recovered and covid uncertainty has receded. Dynamic…

    Robust decision-making under risk and ambiguity
    Maximilian Blesch, Philipp Eisenhauer · 2021 · Econometrics · AI summary available
    Abstract

    Economists often estimate economic models on data and use the point estimates as a stand-in for the truth when studying the model's implications for optimal decision-making. This practice ignores model ambiguity, exposes the decision problem to misspecification, and ultimately leads to post-decision disappointment. Using statistical decision theory, we develop a framework to explore, evaluate, and optimize robust decision rules that explicitly account for estimation uncertainty. We show how to operationalize our analysis by studying robust decisions in a stochastic dynamic investment model in which a decision-maker directly accounts for uncertainty in the model's transition dynamics.

    Nonparametric Tests of Tail Behavior in Stochastic Frontier Models
    William, C. Horrace, Yulong Wang · 2020 · Econometrics · AI summary available
    Abstract

    This article studies tail behavior for the error components in the stochastic frontier model, where one component has bounded support on one side, and the other has unbounded support on both sides. Under weak assumptions on the error components, we derive nonparametric tests that the unbounded component distribution has thin tails and that the component tails are equivalent. The tests are useful diagnostic tools for stochastic frontier analysis. A simulation study and an application to a stochastic cost frontier for 6,100 US banks from 1998 to 2005 are provided. The new tests reject the normal or Laplace distributional assumptions, which are commonly imposed in the existing literature.

    Machine Learning Estimation of Heterogeneous Treatment Effects with Instruments
    Vasilis Syrgkanis, Victor Lei, Miruna Oprescu et al. · 2019 · Econometrics · AI summary available
    Abstract

    We consider the estimation of heterogeneous treatment effects with arbitrary machine learning methods in the presence of unobserved confounders with the aid of a valid instrument. Such settings arise in A/B tests with an intent-to-treat structure, where the experimenter randomizes over which user will receive a recommendation to take an action, and we are interested in the effect of the downstream action. We develop a statistical learning approach to the estimation of heterogeneous effects, reducing the problem to the minimization of an appropriate loss function that depends on a set of auxiliary models (each corresponding to a separate prediction task). The reduction enables the use of all …

    Super-linear Scaling Behavior for Electric Vehicle Chargers and Road Map to Addressing the Infrastructure Gap
    Alexius Wadell, Matthew Guttenberg, Christopher P. Kempes et al. · 2022 · Econometrics · AI summary available
    Abstract

    Enabling widespread electric vehicle (EV) adoption requires substantial build-out of charging infrastructure in the coming decade. We formulate the charging infrastructure needs as a scaling analysis problem and use it to estimate the EV infrastructure needs of the US at a county-level resolution. Surprisingly, we find that the current EV infrastructure deployment scales super-linearly with population, deviating from the sub-linear scaling of gasoline stations and other infrastructure. We discuss how this demonstrates the infancy of EV station abundance compared to other mature transportation infrastructures. By considering the power delivery of existing gasoline stations, and appropriate EV…
