Summary
NERA Economic Consulting case interviews differ from standard management consulting — they emphasize economic reasoning, regulatory knowledge, and quantitative modeling. Full guide.On this page
NERA Economic Consulting is not a management consulting firm in the traditional sense — and if you prepare for NERA interviews like you'd prepare for McKinsey, you'll fail. NERA is an economic consulting firm: it applies rigorous economic analysis to litigation, regulatory proceedings, and corporate strategy. The interview tests economics, not business frameworks.
The candidate who wins at NERA is the one who can explain what a regression analysis shows, discuss why a particular market structure might be anti-competitive, and calculate damages using economic theory — not the one who can draw the best MECE issue tree.
NERA Economic Consulting (National Economic Research Associates) is a global economic consulting firm founded in 1961, now owned by Marsh McLennan. With ~600 professionals across 25+ offices globally, NERA provides expert economic analysis for litigation (antitrust, securities, intellectual property), regulatory proceedings (energy, environment, financial services), and corporate strategy. It is one of the "Big Three" of economic consulting alongside Charles River Associates (CRA) and Analysis Group.
NERA vs. Management Consulting: The Core Difference
Understanding this distinction determines how you prep.
| Dimension | NERA Economic Consulting | MBB Management Consulting |
|---|---|---|
| Core work | Economic analysis for litigation + regulation | Business strategy advice for corporate clients |
| Case output | Expert report, damages calculation, regulatory filing | Strategy recommendation, operational improvement plan |
| Primary methodology | Econometrics, economic theory, statistical modeling | Structured frameworks, hypothesis testing, market analysis |
| Client type | Law firms, government agencies, regulators, corporations in litigation | C-suites of Fortune 500 companies, PE firms, governments |
| Interview focus | Economics fundamentals, quantitative reasoning | Business structuring, case frameworks, hypothesis-driven thinking |
| Typical hire profile | Strong economics undergrads, master's students, PhD economists | MBA graduates, economics/engineering/consulting undergrads |
The economic consulting industry — NERA, Analysis Group, CRA, Cornerstone Research — serves a specialized market that most case interview prep resources ignore. If this is your target, standard case prep is necessary but not sufficient.
The NERA Interview Process
NERA's process varies by office but typically follows this structure:
| Round | Format | Duration | Key Content |
|---|---|---|---|
| 1 | Recruiter screen | 20–30 min | Fit, background, why NERA, timeline |
| 2 | Technical + behavioral | 45–60 min | Economics case or problem, background questions |
| 3 | Final round | 60–90 min | Multiple conversations with Senior Principals/VPs, written exercise (some offices) |
Per Wall Street Oasis candidate reports and Glassdoor, NERA's process is less standardized than MBB. The specific case format depends on which practice group you're interviewing for (antitrust vs. securities vs. energy, etc.).

Practice now →What NERA Cases Actually Look Like
A NERA case is not "a client is losing profitability — how do you fix it?" It's more likely to involve:
Antitrust case example: "Two competing widget manufacturers want to merge. The DOJ is reviewing whether this merger violates antitrust law. What economic analysis would you conduct to assess whether this merger creates anti-competitive harm?"
Strong answer framework:
- Market definition: Define the relevant product and geographic market using the hypothetical monopolist test (SSNIP test)
- Market concentration: Calculate HHI before and after the merger; flag if it exceeds DOJ thresholds (1800 HHI post-merger with delta > 100)
- Competitive effects: Assess unilateral effects (would the merged entity raise prices?) and coordinated effects (does the merger facilitate collusion?)
- Entry analysis: Could new entrants discipline a post-merger price increase?
- Efficiencies: Do cost savings outweigh anti-competitive harm?
This is economic analysis, not a strategy framework. The case interview frameworks complete guide is less relevant here than core microeconomics.
Securities damages example: "Shareholders in a class action allege that a company misled investors about its financial condition, causing the stock price to decline when the truth emerged. How would you calculate damages?"
Strong answer: Apply the event study methodology — isolate the stock price movement attributable to the disclosure (vs. market-wide movement), apply a regression to separate the firm-specific effect, and multiply by shares outstanding. Discuss the "but-for" price concept: what would the price have been absent the fraud?
Key Economic Concepts for NERA Interviews
You should be able to discuss these fluently:
| Concept | Why It Matters at NERA |
|---|---|
| Market definition (SSNIP test) | Core to antitrust analysis |
| HHI (Herfindahl-Hirschman Index) | DOJ/FTC merger review threshold |
| Regression analysis and causality | Damages calculations, event studies |
| Consumer and producer surplus | Regulatory economics, price analysis |
| Price elasticity | Market power analysis, pass-through rates |
| Difference-in-differences | Measuring the effect of regulatory changes |
| Event study methodology | Securities fraud damages |
| Discounted cash flow (DCF) | Financial damages, valuation |
You don't need to be a PhD to discuss these — you need to be able to explain what they measure and why they're relevant in a particular context.
NERA hires people who are comfortable saying "I would use an event study regression to isolate the stock price impact" rather than "I would analyze the financial impact on shareholders." Specificity signals economics training. Vagueness signals that you've studied for the wrong interview.
Behavioral Interview at NERA
NERA's behavioral questions are closer to academia than to consulting. Common themes:
| Theme | Sample Question |
|---|---|
| Research and analysis | "Describe a piece of quantitative analysis you're proud of. Walk me through your methodology." |
| Attention to detail | "Tell me about a time you caught an error in your own or someone else's analysis. What was the impact?" |
| Writing and communication | "How would you explain a regression analysis to a non-economist client?" |
| Why economic consulting | "Why economic consulting rather than PhD economics or management consulting?" |
| Practice area interest | "Which of NERA's practice areas most interests you, and why?" |
The "why economic consulting vs. PhD or management consulting" question is important. Strong answers for economic consulting typically involve: interest in applied economics and real-world impact; preference for varied, project-based work over academic research; interest in the litigation and regulatory context that management consulting doesn't touch.
