요약This dissertation explores how key microeconomic frictions and strategic interactions among firms shape macroeconomic outcomes. Across three chapters, I examine how financial constraints and market structures-particularly those involving imperfect capital markets and strategic product competition-translate into heterogeneous firm behavior and aggregate economic effects. A defining feature of the approach is the combination of granular microdata with structural macroeconomic models, which allows for empirical characterization and quantification of heterogeneous effects across firms and agents, recognizing that distributional differences often drive aggregate dynamics and policy responses.The first two chapters are derived from my Job Market Paper (titled "Personal Finance and Firm Dynamics") and focus on the role of business owners' personal finances in shaping firm creation and development.Chapter 1 leverages unique Norwegian administrative panel data linking the financial characteristics of individuals to the outcomes of the firms they establish, providing novel insights into the role of personal wealth in entrepreneurial success. Despite substantial prior research on financial constraints faced by firms, existing literature has largely overlooked how personal financial conditions of entrepreneurs impact firm dynamics, mainly due to data limitations. By overcoming these constraints with exhaustive data covering the universe of limited-liability corporations (LLCs) matched with detailed owner financials, this study uncovers new stylized facts. Entrepreneurs in the top 1% of the wealth distribution start businesses approximately 5.5 times larger than those established by the bottom 50%. These firms also exhibit lower leverage, rely more heavily on internal finance, and demonstrate higher survival rates and greater capital intensity. These findings critically establish the personal financial heterogeneity of entrepreneurs as a significant determinant of firm-level financial frictions and lifecycle outcomes.Chapter 2 proposes a structural quantitative framework that rationalizes empirical observations from the first chapter, explicitly accounting for unobservable productivity and individual characteristics. My novel framework incorporates heterogeneous agents making occupational choices with distinct entrepreneurial and labor productivity. Contrary to most canonical models of entrepreneurship that implicitly assume either unlimited liability or risk-neutral investors, my framework captures endogenous risk-exposure via explicitly modeling limited liability to reflect realistic risk management between personal and business finances, and through an innovative credit friction mechanism departing from conventional leverage constraints. The model quantitatively demonstrates that financial channels explain nearly half of the medium-run size differences among entrepreneurial firms, primarily driven by liquidity constraints and heterogeneity in marginal propensities to consume. Counterfactual general equilibrium analyses reveal substantial misallocation and negative externalities from excessive entrepreneurial entry under financial frictions, highlighting nuanced implications for wealth redistribution policies such as inheritance taxation and loan subsidies.Chapter 3 shifts the focus to product markets and investigates how strategic incentives of multiproduct firms shape the relationship between market concentration and innovation. Leveraging scanner data and detailed product attributes, the chapter documents three novel empirical patterns: rapid product obsolescence, dynamic adjustments in firms' product portfolios, and a robust inverted-U shaped relationship between competition and innovation. It establishes that firms strategically build up their innovation efforts up to an optimal level. To rationalize these facts, it develops a dynamic oligopoly model where multiproduct firms strategically decide on innovation efforts to enhance existing products or introduce new varieties, competing alongside a fringe of atomistic firms. This structural framework uniquely captures how strategic interactions among multiproduct firms affect innovation incentives, assessing macroeconomic implications of rising market concentration on aggregate innovation and growth.
