Top 20 Economist Interview Questions and Answers for 2022

Multicollinearity

Multicollinearity is a sample phenomenon. It alludes to the fact that the explanatory variables have a linear relationship. Because it will be present in the majority of the samples, it is always more important to consider the severity of presence than just presence.

Causes

  • Often economic data tend to move together.
  • Choice of the sample.
  • Specification of the model.
  • Consequences

  • Estimates have large standard errors if multicollinearity is present in the data. Thus precision of estimates declines.
  • The t-ratios would become insignificant which would lead to the dropping of incorrect variables from the model.
  • The estimated coefficients become sensitive to sample data.
  • It is almost impossible to estimate parameters in the case of perfect multicollinearity.
  • Test / detection

    Regress all X(independent variables) on Y(dependent variable). Pick the X in the model with the highest R-squared value, and then include the X with the second-highest R-squared value. The introduction of a new variable is then known as:

  • Useful, if there is a significant increase in the R-squared value but insignificant in the coefficient estimates of the model.
  • Superfluous, if there is a significant decline in R-squared value and insignificant change in the coefficient estimates of the model.
  • Detrimental, if there is a significant change in the coefficient estimates. This would imply the presence of multicollinearity.
  • Chi-square test to detect the presence of multicollinearity
  • F-Test to locate multicollinearity
  • T-test to detect the pattern of multiplication
  • C. The Variance Inflation Factor, or VIF, is also used to identify multicollinearity. A VIF value of greater than 10 indicates severe multicollinearity.

    Autocorrelation

    It is a phenomenon where the error terms are correlated that is also referred to as serial correlation. It is very common in time-series data.

    Causes

  • Omitted variables
  • Autoregressive lag model
  • Errors in measurement
  • Data manipulation i.e. smoothening of data
  • Consequences

  • OLSE(Ordinary Least Square Estimates) grossly underestimate the variance of the error terms although they are unbiased
  • The variance of the coefficient estimates is underestimated
  • Large t-values imply incorrect conclusions
  • Test / detection

    A. Von Neumann Ratio test

    It uses z-test to check for the presence of autocorrelation. The data have no autocorrelation, which is the null hypothesis. The Von Neumann Ratio is the ratio established by Z in the formula below. For large n (sample size), Z is approximately normal with.

    The following is a list of the Durbin Watson test’s presumptions:

  • There should be no missing observation in the data
  • Necessary intercept term in the model
  • The error terms follow the first-order autoregressive scheme
  • Lagged values of Y(dependent variable) should not be present in the model

    There is an inconclusive region present in this test, which is its only drawback.

    Did you know economics majors can work in a range of fields? This article on economics interview questions and answers will assist you in translating your coursework and experiences into responses! Read on to learn about these frequently asked questions in economics interviews!

    You will typically be asked questions about yourself and why you are a good fit for the position during job interviews. However, economics job candidates will be asked probing questions during interviews about their skills and the field.

    If you’re interviewing for a job in the field of economics, be prepared for extensive case studies. In these interviews, you’ll be given a specific issue to address and a demand response with a workable economics solution.

    These frequently asked questions are intended to gauge general suitability, competence, analytic prowess, and problem-solving skills in economics interviews.

    The below questions are segregated into four sections-

  • General fit for company & position
  • Competency
  • Problem-solving skills
  • Analytical skills
  • I can convey complicated information in an understandable manner, which is my greatest strength as an economist. Throughout my career, I’ve had numerous chances to explain economic concepts and data to the general public, including during public speaking engagements and media interviews. This has assisted me in honing my communication abilities and teaching me how to adapt my language to various audiences. ”.

    You can learn a lot about an economist’s philosophy and values by asking them this question. Additionally, it demonstrates to the interviewer your capacity for independent and creative thought, both of which are crucial capabilities for this position. Try to demonstrate in your response how you can be innovative and creative while also being able to work as a team.

    Employers inquire about your background and potential contributions to learn more about you. Make a list of the qualifications you have for the position before the interview. Concentrate on what sets you apart from the competition and emphasize any transferrable abilities or knowledge that will help you succeed in this position.

    Example: “I am a top student in the economics department. I’ve also completed three internships, giving me practical experience working with experts in the field. I learned how to use financial software to analyze data and interpret information during my internship at a nearby bank. I believe that this quality distinguishes me from other applicants. ”.

    Economic conditions and trends must be studied and analyzed by economists. They make forecasts and recommendations to businesses, governments, and other organizations using this data.

    FAQ

    What are the basic techniques of econometrics?

    Four broad categories of econometric techniques exist: regression, forecasting, descriptive statistics, and hypothesis testing. Descriptive statistics include measures of central tendency, dispersion and distribution. Data scientists frequently use those in exploratory data analysis (EDA).

    How is econometrics used in real life?

    Today, academics and professionals like Wall Street traders and analysts frequently use it. Applying econometrics to the study of the income effect with observable data is one example of its use. An economist might assert that as someone’s income rises, their spending will follow.
