His economic treatise *Nouveaux principes d'économie politique* (1819) challenged the prevailing optimism of classical economists, arguing that unregulated capitalism could lead to overproduction and social inequality. This work distinguished him as a precursor to later critiques of industrialization.

### Legacy and Influence
Sismondi's economic theories resonated with 19th-century socialists and reformers, who drew on his critiques to advocate for workers' rights and state intervention in the economy. His historical methodologies, which integrated economic data with political narrative, set a precedent for later historians. While his direct policy impact was limited during his lifetime, his ideas contributed to the broader shift toward more equitable economic policies in the 20th century.

### Personal Life and Later Years
