This book offers a detailed comparison between "culpa in contrahendo" and "promissory estoppel."
It examines the "culpa in contrahendo," a concept developed within Civil Law systems — especially in Germany, Italy, France, and Spain — together with "promissory estoppel," a figure from Common Law, paying particular attention to its operation in the U.S. legal system.
A key difference lies in the third type of "culpa in contrahendo," which requires proof of "bad faith" to claim damages — a condition absent in "promissory estoppel," which thus becomes a more effective and fairer instrument before the courts.
The second aspect of "culpa in contrahendo," related to consumer protection and the duty to inform buyers before concluding a contract, is comparable to "misrepresentation" in Common Law.
This topic was the subject of William R. Lizárraga Ugarte's doctoral research at the Universitat Autònoma de Barcelona, where he analyzed 1,000 Common Law cases and 500 Civil Law cases from Spain, Italy, Germany, and France.
Volume I: Core analysis and comparative framework.
Volume II: Civil Law cases (Germany, Italy, Spain, France) analyzed from the perspective of Promissory Estoppel.
Volume III: Promissory Estoppel cases (mainly from Common Law systems) analyzed from the standpoint of Culpa in Contrahendo. |

"Success and You" (1993). Arequipa, Peru: Publiunsa Press.
|
|
| Beyond the common vision that equates success with the accumulation of wealth, this book invites readers to look deeper. True success does not consist merely in acquiring material goods, but in embracing and embodying the principles that allow us to achieve dreams and goals in harmony with society. It is a modern GPS that brings together the best of existentialist, Buddhist, Christian, and metaphysical philosophy.

This is not just another "how to succeed" book. It is about a dream — a young man's dream of receiving a letter from Success itself. In that letter, Success speaks to the reader as a father to a child, offering guidance on how to govern life with discipline, clarity of purpose, and strategies to reach one's goals. It is not only about money: it is about building a purposeful path, living within ethical boundaries, and contributing to the common good.
Inspired by Khalil Gibran's "The Prophet", the Hindu "Bhagavad Gita", and Kant's categorical imperative, this book proposes principles for life, family, and community. In essence, it is a universal letter — a message that transcends the individual and becomes a call to humanity.
Originally published in 1993, this book has accompanied thousands of readers as a practical and spiritual guide to redefining success. More than a manual, it is a compass for life — a constant companion inspiring readers to live with purpose, ethics, and fulfillment. |

"Tax Sparing Credits (CTS) in the Free Trade Area of the Americas" (2005). Arequipa, Peru: Editorial Fund of the Arequipa Bar Association.
|
|
| This book addresses one of the most complex and debated topics in International Tax Law: "tax sparing credits". With a rigorous academic approach, William R. Lizárraga Ugarte examines the relevance of tax sparing within the framework of the Free Trade Area of the Americas (FTAA), analyzing its impact on foreign direct investment, fiscal incentives, and the negotiation between developed and developing countries.

The book presents an in-depth study based on the author's Master's thesis in Tax Law at the University of Florida, translated into Spanish by the author himself. Using a "trialist" method that integrates norms, behaviors, and values, he offers a comparative study of U.S., Canadian, European, and Asian policies, highlighting the inconsistencies of U.S. policy compared to more flexible international positions.
Beyond its technical rigor, the work serves as a reflection tool for lawyers, economists, academics, and policymakers interested in the intersection between globalization, taxation, and economic development in Latin America and the Caribbean.
