Dynamics of High‐Growth Young Firms and the Role of Venture Capitalists

International Economic Review, EarlyView.
ABSTRACT Motivated by the substantial growth and upfront investments of venture capital (VC)‐backed firms observed in administrative US Census data, this study develops a life‐cycle firm dynamics model. In the model, startups choose the source of financing from VC, angel investors, or banks, depending on their growth potential, and invest in innovation.

A Comparative Review of Specification Tests for Diffusion Models

International Statistical Review, EarlyView.
Summary Diffusion models play an essential role in modelling continuous‐time stochastic processes in the financial field. Therefore, several proposals have been developed in the last decades to test the specification of stochastic differential equations.

Standing on a common ground: a comparison of static stability approaches for pallet loading

International Transactions in Operational Research, EarlyView.
Abstract At the practical level, the static stability constraint is one of the most important constraints in practical pallet loading problems, such as air cargo palletizing. Approaches to modeling static stability, which range from base support and mechanical equilibrium calculations to physical simulation, differ in workflow, focus, and assumptions ...

Monetary Policy When Preferences Are Quasi‐Hyperbolic

Journal of Money, Credit and Banking, EarlyView.
Abstract We study discretionary monetary policy in an economy where economic agents have quasi‐hyperbolic discounting. We demonstrate that a benevolent central bank is able to keep inflation under control for a wide range of discount factors. If the central bank, however, does not adopt the household's time preferences and tries to discourage early ...

New formulas of Euler's number e

Euler's number e(≒2.718281) is the base of a constant exponential function that does not change upon differentiation, and it is a very important constant frequently used in physical phenomena such as the motion of objects and electrical circuits.

CBDC as Imperfect Substitute to Bank Deposits: A Macroeconomic Perspective

Journal of Money, Credit and Banking, EarlyView.
Abstract The impact of Central Bank Digital Currency (CBDC) is analyzed in a closed‐economy model with monopolistic competition in banking and where CBDC is an imperfect substitute with bank deposits. The design of CBDC is characterized by its interest rate, its substitutability with bank deposits, and its relative liquidity.
